Intro There has been a lot of hype on socials recently about MCP or Model Context Protocol. Essentially it's a protocol that allows LLM AI to be extended. Most of the extensions relate to providing context using your own data. This is what I am going to walk through here. I will walk through: Creating an MCP What works and what works better My discoveries so far If you just want the code - it's here: https://github.com/codecowboydotio/mcp-server-examples The reason I decided to initially play around with MCP was because I had a high level of scepticism regarding it. I've seen a LOT of posts on the internet that talk about it, how it's transformational and so on. I thought to myself "I'm going to look into this, but I'm going to do it bottom up and by writing a server". The following d…  ( 9 min )

In the competitive world of e-commerce, monitoring prices on platforms like Amazon is crucial for businesses and savvy shoppers alike. However, scraping data directly from such websites can lead to IP bans and access restrictions. To mitigate these risks, using Python in conjunction with proxy IPs offers a safe and effective solution for price monitoring. Why Use Proxies for Amazon Price Monitoring? Anonymity: Proxies mask your real IP address, making it difficult for websites to track your scraping activities. import requests proxy = { http://your_proxy_ip:port", http://your_proxy_ip:port" def get_price(url): # Find the price element (this may vary based on the product page) url = 'https://www.amazon.com/dp/your_product_id' Static and Residential IPs: These are less likely to be flagged by Amazon. Conclusion For more information on reliable proxy services, consider checking out IP2World and explore their offerings tailored for your needs. Happy scraping!  ( 4 min )

When working with Django ORM, you might encounter the need to retrieve distinct records, especially when filtering on a column such as sku. However, you may run into a specific issue if you aim to sort by another column, like id. This article will cover why this error arises and how you can solve it effectively. Understanding the Problem The error you encountered, django.db.utils.ProgrammingError: SELECT DISTINCT ON expressions must match initial ORDER BY expressions, occurs because of the specific SQL syntax requirements when using DISTINCT ON() in combination with an ORDER BY clause. When you apply DISTINCT ON, the PostgreSQL database expects that the column specified in DISTINCT ON appears at the beginning of the ORDER BY clause. Because your query orders by id after using DISTINCT ON(s…  ( 4 min )

连续分享了几天的Uniapp跨平台开发鸿蒙应用教程的文章，相信大家对跨平台开发已经有了初步的了解，今天分享一下跨平台开发中的自定义导航栏。 在Hbuilder的初始化项目中是自带了导航栏的，这是一个全局的导航栏，它的样式设置和修改是在全局的配置文件pages.json中进行。 现在打开pages.json文件，在globalStyle中有一些关于导航栏的属性，我们尝试修改一下： { "pages": [ //pages数组中第一项表示应用启动页，参考：https://uniapp.dcloud.io/collocation/pages ], "globalStyle": { 然后看到导航栏已经发生了改变： 这样的修改很方便很便捷，但是好像只有颜色和文字这些基础的属性可以修改，很多时候我们需要在导航栏上添加一些组件，比如按钮或者搜索框。 对于这种情况，uniapp也提供了相应的设置方案，还是在pages.json文件中，当我们需要为某一个页面的导航栏添加组件，就在对应的path路径下设置style，style中有个titleNView属性就是为导航栏添加自定义组件，像这样： "path": "pages/index/index", 但是幽蓝君亲测这种设置方式在浏览器运行时可以正常显示，在鸿蒙中是无效的： 所以在鸿蒙开发中我们需要自己定义导航栏。 再次回到pages.json文件，这次将navigationStyle设置成custom，作用是取消原生的导航栏： "path": "pages/index/index", 然后打开需要自定义导航栏的页面，我这里就直接在首页index.vue中操作，实现逻辑比较简单，就是在页面顶部添加一个导航栏大小的组件，然后在其中添加搜索框，相关代码如下： style="width: calc(100% - 40px);background-color: white;height: 35px;padding: 0px 10px;border-radius: 18px;" .custom-nav-bar { / background-color: #f8f8f8; 导航栏背景色 / 其他样式属性 */ 看一下运行效果： 今天就以添加一个搜索框为例，大家如果需要自定义其他的样式也是类似的实现方式。 以上就是uniapp跨平台开发鸿蒙应用中的自定义导航栏，感谢大家的阅读。  ( 3 min )

Most people think hacking is just about tools, code, or some flashy terminal with green text flying by. But that’s not what makes a real hacker. Let me tell you what really matters—the part only 1% truly understand… Forget the tools for a second. Real hacking starts when you ask the questions nobody else is asking: "Why does this work like that?" "What happens if I try something they didn’t expect?" "What’s behind this system they don’t want me to see?" It’s about curiosity. Obsession. Even rebellion. Not following tutorials step-by-step, but breaking patterns and learning how systems truly work under the surface. I’m teaching myself Python and networking— Not because I want to show off, but because I want to understand how the internet and machines actually think. I’m not here to be just another script kiddie. I’m building a foundation. Quietly. Daily. I don’t want fame. I don’t want likes. I want leverage. I want to be the kind of person who sees through the system—and knows how to bend it. A silent weapon. Sharp, skilled, and always learning. Are you learning just to pass exams? Or are you learning to break limits? Be real with yourself. The world’s already full of followers. We need more builders, breakers, and thinkers. If you feel that fire too—the curiosity, the hunger to really understand—drop a comment. Tell me what you're working on. I’m still early in my journey, but I’m in it for real. Let’s learn. Let’s grow. Let’s hack.  ( 3 min )

Introdução Com a expansão dos serviços on-line, surge uma demanda cada vez maior por sistemas responsivos, performáticos e de alta capacidade de escalabilidade. O uso da programação assíncrona se mostra muito eficaz na obtenção destes atributos de qualidade durante o desenvolvimento de um software. Este artigo busca mostrar os benefícios e os contrapontos do uso da programação assíncrona em Python em sistemas "I/O-bound" (altamente dependentes de input e output) e outras tarefas que necessitam de execução paralela. Conceitos de programação assíncrona Computadores executam softwares de forma sequencial, isto é, uma instrução após a outra. Um software geralmente realiza múltiplas tarefas, e nem sempre faz sentido esperar que uma tarefa termine antes de iniciar a próxima (SKVORTSOV, 2021). Se…  ( 5 min )

RESUMO Palavras-chave: Arquitetura REST. Sistemas distribuídos. API. HTTP. Serviços Web. 1 INTRODUÇÃO 2 DESENVOLVIMENTO De acordo com Stein Junior (2021), REST surgiu da necessidade de criar interfaces simples e eficientes para a comunicação entre sistemas, principalmente via web. O autor afirma que "o objetivo era criar interfaces simples, escaláveis e independentes, facilitando a comunicação entre sistemas distribuídos por meio do protocolo HTTP" (STEIN JUNIOR, 2021, p. 10). A arquitetura REST é baseada na manipulação de recursos — objetos ou entidades de informação — que são identificados por meio de URIs (Uniform Resource Identifiers) e manipulados utilizando métodos HTTP padronizados, como GET, POST, PUT e DELETE. Fielding (2000) ressalta que uma das principais características do REST…  ( 6 min )

Introduction In the world of numerical computing, transitioning from NumPy to JAX can offer significant performance benefits thanks to JAX's Just-In-Time (JIT) compilation and optimizations for GPU acceleration. However, this transition isn't always smooth for all operations, particularly for those that are heavily transformation-based, such as broadcast_to and moveaxis. In this article, we will explore why these functions may perform slower in JAX compared to NumPy and discuss best practices to optimize their usage. Understanding the Performance Discrepancy Why JAX May Be Slower for Basic Operations The performance of JAX can vary significantly depending on the operations being performed. While JAX is designed for efficient numerical computation and can excel in larger batch sizes and com…  ( 5 min )

Let’s not sugarcoat it—workflow automation should be simple. You sketch out a flow, wire up a few APIs, slap in a trigger, and boom: your job runs itself while you sip coffee. Except… not really. In reality, automation breaks. It misfires. It fails silently. And if you’re building workflows without a plan (I’ve done it), you’ll spend more time debugging than you ever saved. So here are 5 workflow automation mistakes I’ve run into—plus how I fixed them using Martini, a low-code automation platform that somehow gets it. 1. Only Building the Happy Path Raise your hand if you’ve built an automation that worked perfectly—until the first error. I’ve done it. Then I spent the next hour trying to figure out why a webhook timed out and brought down the entire flow. ✅ Fix: Build for failure first.…  ( 4 min )

Tinian, a small island in the US territory of the Northern Mariana Islands, could get a second chance at launching a stablecoin after the territory’s Senate voted to override the governor’s earlier veto of its stablecoin bill. On May 9, the Northern Mariana Islands Senate voted 7-1 to override Governor Arnold Palacios' April 11 veto of the bill, which would allow the Tinian local government to issue licenses to internet casinos and includes a provision for the Tinian treasurer to issue, manage and redeem a “Tinian Stable Token.”  The bill will now head to the 20-member Northern Mariana Islands House, which will need a two-thirds majority vote to override the veto and pass the bill into law. If the House is quick to pass the bill, the Tinian government could be in the lead for the first US …

Censorship-resistant “dark stablecoins” could come in increasing demand as governments tighten their oversight of the industry.  Stablecoins have been used for various groups to store assets due to a lack of government interference; however, with regulations pending, that could soon change, Ki Young Ju, CEO of crypto analytics firm CryptoQuant, said in a May 11 X post. “Soon, any stablecoin issued by a country could face strict govt regulation, similar to traditional banks. Transfers might automatically trigger tax collection through smart contracts, and wallets could be frozen or require paperwork based on government rules,” he said. “People who used stablecoins for big international transfers might start looking for censorship-resistant dark stablecoins instead.” On the heels of US Presi…

Hardware wallet provider Ledger has confirmed its Discord server is secure again after an attacker compromised a moderator’s account to post scam links on May 11 to trick users into revealing their seed phrases on a third-party website. “One of our contracted moderators had their account compromised, which allowed a malicious bot to post scam links in one channel,” Ledger team member Quintin Boatwright wrote on the Ledger Discord server.  “The issue was quickly contained: the compromised account was removed, the bot was deleted, the website was reported, and all relevant permissions were reviewed and secured.” Some members in Ledger’s Discord channel claimed the attacker abused moderator privileges to ban and mute them as they tried to report the breach, possibly slowing Ledger’s reaction.…

How to Send Traces Using Scala and OpenTelemetry When working with distributed systems, traceability is crucial for understanding system behavior. If you are using Scala and OpenTelemetry to send traces, you may encounter some challenges, particularly if your traces are not appearing in the tracing backend like Zipkin or Tempo. Why Might Traces Not Be Sent? Traces not appearing in your tracing backend can be attributed to several issues. These issues might stem from misconfiguration in your OpenTelemetry setup, lack of proper attributes, or even potential threading issues with Scala. It’s essential to verify that the OpenTelemetry collector is up and running and that the endpoint is correctly configured, which you have indicated is ready. In Scala, the ThreadLocal context propagation can b…  ( 5 min )

1 INTRODUÇÃO No desenvolvimento de Software, a definição de uma arquitetura sólida é fundamental para assegurar que o sistema evolua de maneira organizada, escalável e sustentável. Dentre os modelos arquiteturais existentes, a arquitetura em camadas, de acordo com Gallotti (2017), “a separação e independência são conceitos essenciais para uma boa arquitetura”. Este artigo tem como objetivo elucidar de maneira abrangente a Arquitetura em Camadas, abordando vantagens, desvantagens, aplicações práticas e exemplos concretos. A arquitetura em camadas organiza o sistema com as funcionalidades associadas a cada uma. Cada camada fornece serviço para a camada acima dela, sendo assim as camadas inferiores representam os serviços essenciais do sistema. Essas camadas são projetadas para serem móve…  ( 5 min )

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Crushing the Command Line I created envguardr, a CLI tool that validates environment variables at build time. It’s useful for projects where .env files or runtime checks aren't enough. It handles types, required fields, and default values, but I felt it needed more flexibility. To address that, I enhanced the underlying validation package valitype by adding support for custom validators. This was one of the ideas suggested by Amazon Q Developer during the challenge. That single improvement unlocked a range of advanced use cases. Install envguardr globally: $ npm install -g envguardr Create an env.schema.js file with custom validation logic: module.exports = { API_KEY: { type: 'custom', validator: (v) => /^[a-z0-9]{16}$/.test(v || ''), errorMessage: 'API_KEY must be 16 alphanumeric characters', required: true } } Then run: $ envguardr validate env.schema.js envguardr with a custom schema validation for API_KEY: https://github.com/fontebasso/valitype https://github.com/fontebasso/envguardr This challenge was my first experience with Amazon Q Developer, and I was genuinely impressed. It’s exactly the kind of tool I always felt was missing for developers working with AI. Amazon Q Developer was able to read my codebase, understand its context, and assist in meaningful ways. It helped me improve typing, write better tests, fix subtle lint issues, and explore useful new features. From the several improvements it suggested for valitype, I chose to implement custom validators. That feature alone made envguardr much more powerful, giving it the flexibility needed for advanced configuration validation.  ( 3 min )

In Perl programming, naming conventions for symbol table entries can seem confusing at first glance, especially when we encounter entries like Test_two and A_Package::Test_one. In this article, we will explore the distinctions between these two styles of naming and how they impact the scope and accessibility of your subroutines. Understanding Symbol Tables in Perl In Perl, every package has its own symbol table, which serves as a collection of all the symbols (subroutines, variables, etc.) defined within that package. This allows for the organization of code into different namespaces, ensuring that subroutine names do not clobber each other in larger applications. The Significance of Test_two When we define a subroutine using the name Test_two, like this: *{"Test_two"} = sub{"Testing Two…  ( 4 min )

Server Permissions: The server might not have the permissions set to allow …  ( 4 min )

Gland: Beyond Protocol-Agnostic Hey everyone, I’m back again with another update from the world of Gland — and this one is kinda big for me. So far, I’ve talked a lot about Gland being protocol-agnostic. But recently, something shifted. Gland is not just protocol-agnostic anymore — it’s kinda framework-agnostic too. What does that even mean? Let’s be real: right now Gland doesn’t care whether you're using Express, Fastify, Hono, or literally anything else that can act like an HTTP server. You can swap them in and out with minimal effort. And I’m not talking about some theoretical plug-and-play thing. I mean actual working code. Take this simple example: glandjs/gland/main/samples/01-simple/src/main.ts In this setup, I’m using Express. But if you want Fastify instead? Just do this: async fu…  ( 5 min )

JavaScript is a single-threaded, synchronous programming language at its core, but it handles asynchronous operations through clever mechanisms like the event loop. To truly understand how JavaScript works under the hood, you need to grasp two fundamental concepts: execution context and the call stack. An execution context is an abstract concept that holds information about the environment where JavaScript code is executed. There are three types of execution contexts in JavaScript: Global Execution Context: Created when the JavaScript engine first starts executing your code Function Execution Context: Created whenever a function is invoked Eval Execution Context: Created inside an eval function (rarely used) Each execution context has two phases: Creation phase Execution phase During the c…  ( 5 min )

🚀 Stepping Into the Cloud: My First Tech Internship I’ll be working remotely as a Cloud Engineering Intern at a startup called Pledged. They’re doing some really cool work helping universities and colleges manage their partnerships with external companies.

You would think that a small comment you made about your partner's outfit does not mean anything. However, that small comment has the potential to become a trauma for your partner. In fact, any comment that comes out of your mouth has the potential to scar your partner for life. Therefore, it is important to know yourself, know the evil and good side of your personality, know when each of those are in command of your speech. This knowledge will in turn make you a safe space for your partner, and will also make you someone that is able to prevent conflicts; "If I am aware of my mood I am able to manipulate my speech".

When scripting in Bash, it's common to want to exit a script gracefully when an operation fails. This is essential for ensuring that your script does not continue to run in an erroneous state. In this article, we’ll explore how to exit a Bash script with a custom error message and discuss some common pitfalls that may arise in the process. Understanding the Basics of Exit Codes in Bash Bash scripts use exit codes to indicate completion status. A successful command returns an exit code of 0, while a failure returns a non-zero exit code. You can capture this behavior using conditional statements. For example, command || echo 'Error message' will output the error message if the command fails.

In Ecuador, public data systems are becoming increasingly accessible, and developers have a unique opportunity to create tools that make this data more user-friendly. One such system is the ANT matrícula, which allows individuals to check the legal status of a vehicle by entering its license plate. This system is crucial for verifying vehicle registration, ensuring that taxes are paid, and checking whether there are any fines or restrictions on a vehicle. While the ANT does not provide a public API, developers can still create tools that simulate this functionality. For instance, a backend system can be built using technologies like Node.js, where users can input a license plate number and receive data about its registration status. This not only helps users avoid scams when buying a used car but also assists businesses in managing vehicle fleets or ensuring compliance with national regulations. However, it's important to follow ethical guidelines when accessing public data. Developers should ensure that personal data is never stored without consent and that scraping or data collection is done in compliance with legal standards. Creating tools based on the ANT National Transit Authority matrícula system brings significant value to users, especially by saving them time and offering an easy way to confirm the legal status of a vehicle without having to visit government websites.

I. Preface: «Guiding the blind (or pretending to be one?)» Do you enjoy being mistrusted? Think back to that feeling when you tackle a new, intriguing task — whether it’s assembling a complex model, solving a puzzle, or finding your way along an unfamiliar route—and someone hovers over your shoulder. They prompt every step, point out the obvious, never give you a chance to trip, to ponder, to find the solution on your own. Annoying, isn’t it? It feels as though they take you for a fool who can’t put two and two together without outside help. Perhaps I don’t understand something about life. Maybe today’s world really does demand maximum safety and the minimization of any effort or risk. But when I look at the game industry — especially its mainstream sector — I see a trend I’d call desig…  ( 55 min )

For years, create-react-app (CRA) was the go-to tool for spinning up new React projects. With a single command, you could scaffold a full React application complete with Webpack, Babel, ESLint, and more—all without touching a configuration file. But as the React ecosystem rapidly evolves in 2025, developers are asking: Is create-react-app deprecated? 🛑 The Short Answer: Not Officially, But Practically... Yes create-react-app has not been officially deprecated by its maintainers, it’s clear that active development has stalled. The React team has shifted focus to modern full-stack frameworks, and CRA is no longer the recommended way to start a new project. In other words: CRA still works, but it’s outdated, and better options now exist. 1. Stagnant Development 2. No Server-Side Rendering (S…  ( 5 min )

Payment is one of the problems in online business and Stripe quick emerged as the main payment system despite seen a fair amount of complains. After Marc Louvion released ByeDispute, I was intrigued that Stripe was not covering that and so ended up having a tunnel on card fraud and how Stripe works. Yes Stripe Radar exists and cover some fraud cases but does not cover everything and there have been complains of account flagging despite it or a modification of the fraud detection algorithms that blocks all in coming transactions without any possibilities to stop that. But also fake signups, trial/refund cycling, scraping, or promo code abuse. Enterprise tools are overkill, and DIY solutions eat up dev time. So I wonder if a more general product that check One-trial-per-user, detect disposable email and scraping, have behavioral bot checks, prevent promo/referral abuse and chargeback/refund patterns, ... Would actually be more interesting. When flagging you would get the reasons and the solution can be disactivated at any time. Maybe even a community side with common ban list on fraudulent payments or disputes. On top of that a dashboard to follow all of this. Would something like this be helpful or just more noise? Curious if others have had to roll their own systems for this.  ( 3 min )

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Crushing the Command Line I created an AI Debugging and Automated Refactoring Assistant, a powerful command-line tool built with TypeScript that helps backend developers automatically detect, explain, and fix issues in their projects. This tool scans your code using TypeScript, ESLint, and test runners, and when errors are found, it integrates with Amazon Q Developer CLI to offer intelligent explanations and suggestions directly from the terminal. It solves the common pain point of context-switching between terminal and browser or IDE for debugging — bringing AI assistance to the CLI where developers spend a lot of time. npx ts-node src/index.ts ./src Detects and displays TypeScript, ESLint, and test errors Prompts to open q chat using Amazon Q Developer CLI Provides AI explanations for faster debugging without needing an IDE If you can't run it, here's a short video demo GitHub: https://github.com/gulzerr/crush-review License: MIT Amazon Q Developer CLI's q chat was the key integration for this tool. Once errors are found using static analysis or test execution, the tool automatically invokes the following command: q chat --trust-all-tools --no-interactive This opens a non-interactive (--no-interactive) session in the terminal: It explain linter errors Provide suggestions on how to refactor or fix the code And makes the necessary changes where needed as --trust-all-tools does these changes This is just a simple idea of what we can do using the Q Developer CLI; many more things can be done using this fascinating CLI. Tips: You can pipe files or error messages into q chat for detailed discussions. Combine this tool with CI/CD to flag and debug errors more intelligently. This tool works great in terminal-first workflows or headless environments.  ( 4 min )

There’s something about this special sub-set in the integers set known as prime numbers, unyielding and yet endlessly mysterious. It feels deeply personal. As if the integers are whispering ancient secrets through a language only a few are tuned to understand. Where others have seen chaos, I see some scattered patterns beckoning us to listen more differently and closely. This is my journey, not a conclusion, but a conjecture, a set of observations, a map for others and me to carry further into the unknown. I began with a simple, persistent question: “How can I find the nth prime number?” At first glance, this might appear naïve. It is a question that has echoed through centuries, from the classrooms of ancient Alexandria to the chalkboards of modern-day mathematicians. But in that moment, …  ( 5 min )

Originally posted here In this short post, I'll share with you a simple pattern I use to centralize error handling for my HTTP handlers. If you've written any amount of Go HTTP servers, you've probably gotten tired of writing the same error handling code over and over again: func SomeHandler(w http.ResponseWriter, r *http.Request) { data, err := fetchSomeData() if err != nil { http.Error(w, "Failed to fetch data", http.StatusInternalServerError) log.Printf("Error fetching data: %v", err) return } // More if-err blocks... } This code is repetitive, error-prone, and clutters your handlers with boilerplate instead of business logic. The core idea is simple: change your handlers to return errors instead of handling them directly. package httperror im…  ( 4 min )

In software design, some objects are meant to be shared across the entire application. Think of a configuration manager, a database connection, or a logger. You don’t want to create multiple instances of these — just one that is reused everywhere. That’s exactly where the Singleton Pattern comes in. The Singleton Pattern ensures that a class has only one instance and provides a global point of access to it. It’s part of the Creational Design Patterns — patterns focused on object creation. Think of a government. There’s only one Prime Minister (ideally 😄). If you try to create a new one, it should refer to the existing one. Database connections Logging services Config/environment managers Thread pools Caching mechanisms class Singleton { constructor() { if (Singleton.instance) { return Singleton.instance; } this.timestamp = new Date(); Singleton.instance = this; } getTime() { return this.timestamp; } } // Usage const a = new Singleton(); const b = new Singleton(); console.log(a === b); // true console.log(a.getTime() === b.getTime()); // true class Singleton: _instance = None def __new__(cls): if cls._instance is None: cls._instance = super(Singleton, cls).__new__(cls) cls._instance.timestamp = "Created at instance creation" return cls._instance # Usage a = Singleton() b = Singleton() print(a is b) # True Controlled access to a single instance Saves memory (especially useful for expensive objects) Can be lazily loaded (created only when needed) Global state can be hard to test Can violate Single Responsibility Principle In multithreading environments, needs proper locking (especially in Java/C++) Keep it stateless if possible Avoid abusing it like a global variable Be cautious in multi-threaded apps (use locks/mutexes) The Singleton Pattern is a handy tool when you need exactly one instance of a class to coordinate actions across the system. Use it wisely and you’ll make your application more efficient and structured.  ( 3 min )

This can lead to inconsistent behavior, where the dropdown button only works after a second modal closure, suggesting that the D…  ( 4 min )

Setting up a monitoring stack in Kubernetes can be overwhelming if you're doing it for the first time. When I started working with Azure Kubernetes Service (AKS), I realized I needed better visibility into pod and node metrics — that’s when I turned to Prometheus and Grafana. In this post, I’ll walk you through the exact steps I took to get Prometheus and Grafana running on AKS, along with some lessons I learned along the way. ## 🔧 Why Prometheus + Grafana? Prometheus scrapes and stores time-series data from Kubernetes. Grafana gives you beautiful, customizable dashboards. Together, they provide powerful insights into your cluster’s performance. ## 🛠️ Prerequisites Azure CLI installed and authenticated kubectl configured to your AKS cluster Helm 3 installed A working AKS cluster bash helm repo add prometheus-community https://prometheus-community.github.io/helm-charts helm repo add grafana https://grafana.github.io/helm-charts helm repo update **Install Prometheus:** helm install prometheus prometheus-community/prometheus \ --namespace monitoring --create-namespace Install Grafana: helm install grafana grafana/grafana \ --namespace monitoring Access the Grafana UI: You can port-forward and access Grafana at http://localhost:3000: kubectl port-forward svc/grafana 3000:80 -n monitoring **Login using:** Username: admin Password: (from step 4) **📊 Importing Dashboards** Once inside Grafana, go to "Dashboards > Import" and use IDs from Grafana.com like: Kubernetes Cluster Monitoring: 315 Node Exporter: 1860 **💡 Lessons Learned** Always install Prometheus before Grafana if you want dashboards to auto-discover data sources. Use persistent volumes for Prometheus and Grafana in production. Set up alerts for critical metrics like pod restarts or high CPU usage. I’m planning to extend this by: Setting up AlertManager Integrating with Slack for alerts Enabling SSL and Ingress for Grafana Stay tuned! 👀  ( 3 min )

Introduction In data analysis, it's common to aggregate data from various tables. In your case, you're working with two fact tables, CDI and Population, in DuckDB. You want to perform a filtered aggregation on the Population table based on values from each row in the CDI table. This kind of task can be achieved using ANSI SQL, and I’ll walk you through how to implement it. Understanding the Tables Before diving into the SQL query, let's break down the tables you are using: CDI Table: This contains various categorical data that you'll be using as filters. Population Table: Contains population data that you'll aggregate based on the criteria defined in the CDI table. You have already successfully created your joins with the respective dimension tables, which is great. Now, let's build this f…  ( 4 min )

🌟Let's understand the concept of virtual cluster inside a "physical cluster in K8S !!"🌟 When we are working with a large account/organization we generally come across different types of teams/applications but everything in a single large cluster???? sounds make it very difficult to even imagine. What if we have an isolation between all those and draw some boundaries, set limits and organize?, There comes a topic called "𝑵𝒂𝒎𝒆𝑺𝒑𝒂𝒄𝒆" ✨ What is it ? 2️⃣ It is a way to divide one physical/main cluster into multiple virtual clusters and provides logical boundaries within the cluster and isolates the resources from being mismanaged.

When human relationships are so complex and temporary and painful, it's no wonder that people are becoming more emotionally invested in AI. Whether they are companions or one-night digital stands, the psychology of being emotionally invested is an incredible field to follow. What does it mean to bond? Why seek out AI after having been ghosted in one's dating history? People are experiencing more and more enticing conversations with AI, and the real and ephemeral world become increasingly intertwined. Therefore, psychologists have found out more and more about the need for connection through conversational AI. What was once a game has become an incredibly realistic situation. We're biologically programmed to bond with other humans - it's a survival tactic that's helped our species thrive fo…  ( 6 min )

Introduction Redis is a fast, in-memory data store widely used for caching, message brokering, and real-time analytics. While Redis is incredibly efficient, network overhead can become a bottleneck when a large number of commands are sent sequentially. This is where Redis pipelining comes in. Redis pipelining allows a client to send multiple commands to the server without waiting for individual responses. The server processes the batch of commands and returns all responses in a single reply, significantly reducing the latency caused by round-trip communication. If you are struggling to remember redis commands then this cheatsheet might help you. Redis pipelining offers several advantages: Reduced Latency: By sending multiple commands in a single request, you cut down on network round-tri…  ( 4 min )

My Two Favorite MCP Tools - True Game Changers I've been building custom MCP tools for a month or so now, and just two of them have absolutely transformed how I work with Claude - they were the real 'aha!' moment for me and 'agentic' workflows.

Gland: Beyond Protocol-Agnostic Genix ・ May 11 #opensource #programming #typescript #techtalks  ( 2 min )

Hey everyone, I’m back again with another update from the world of Gland — and this one is kinda big for me. So far, I’ve talked a lot about Gland being protocol-agnostic. But recently, something shifted. Gland is not just protocol-agnostic anymore — it’s kinda framework-agnostic too. What does that even mean? Let’s be real: right now Gland doesn’t care whether you're using Express, Fastify, Hono, or literally anything else that can act like an HTTP server. You can swap them in and out with minimal effort. And I’m not talking about some theoretical plug-and-play thing. I mean actual working code. Take this simple example: glandjs/gland/main/samples/01-simple/src/main.ts In this setup, I’m using Express. But if you want Fastify instead? Just do this: async function bootstrap() { const app…  ( 5 min )

Introduction For years, React Native developers working on iOS have relied on one command more than any other: cd ios && pod install This command has been a staple for managing native dependencies in iOS projects. But in 2025, React Native is moving away from it—and for good reasons. If you’ve recently seen a warning like: "Calling pod install directly is deprecated in React Native" ...you’re witnessing a significant shift in how React Native handles iOS builds. React Native is undergoing a significant transformation, and part of that involves reducing reliance on iOS-specific tools like CocoaPods. Here’s why: CocoaPods is great for iOS, but React Native aims for true cross-platform development. The new architecture favors tools that work seamlessly across iOS, Android, and beyond.

Finding the second highest average mark among students can be a common requirement in many applications that deal with student data. In this article, we will explore a solution to find the student with the second highest average mark without creating any new objects. We will be using Java streams and our custom Student class, which holds information about each student such as their average mark, first name, last name, and date of birth. Understanding the Problem To tackle this problem, we need to follow a few key steps. First, we need to sort the list of students based on their averageMark. Since we want to find the second highest average mark, it is essential to sort the list in descending order. According to the problem's requirements, if two students have the same average mark, we shoul…  ( 4 min )

Hi, my name is Anton. I'm a software developer specializing in cross-platform mobile development, currently working at a fintech company where I help build a neo-banking application. There's often debate about design patterns—do we really need them, or are they just outdated theory with little practical value in modern software development? I strongly disagree with the idea that patterns are unnecessary. In my view, having a solid foundation in theoretical concepts is extremely valuable. It's like recursion: you might not need it every day, but when you encounter a problem that is recursive in nature—like traversing a file system—you simply can't solve it effectively any other way. The same applies to design patterns. Some processes naturally fit certain patterns, and recognizing them allo…  ( 9 min )

How Your Code Became Someone Else’s Goldmine In the thickening jungle of AI innovation, Model Context Protocol (MCP) aggregation services are rising like monolithic temples, promising universal access to tools and automation. On the surface, it sounds utopian—a meritocratic open-source dream. Dig just below, however, and an unsettling reality emerges: these aggregators are monetising the sweat, intellect, and creative risk of thousands, sometimes millions, of individual developers. The winds have changed. Your code—once a byword for progress—has become just another commodity, fuelling centralised profit with little return for its creators. This is the story of a digital gold rush where the diggers now find themselves locked out of the vault. Remember the wild dawn of open source, when so…  ( 9 min )

We want to manage state, by dividing it into units and giving them a name. Attaching behavior to them is also a good option - and thus we have OOP. But let's not adopt it blindly - a critical examination is in order. OOP is there to promote Encapsulation, Polymorphism, Abstraction. What would be the optimal way of providing them? Encapsulation means exposing only as much information about the object as necessary to provide the service. All of the information that is exposed and used by clients, if it were to be changed, means that either the client has to change at the same time - or versioning would need to take place. This idea makes sense, and for a language to support it, it would need ways to mark visibility of fields and methods. Polymorphism means for the same object to exhibit diff…  ( 5 min )

It is difficult to claim that any system or program is completely secure. All of them may contain potential vulnerabilities - errors made during the development process - that can lead to serious consequences. Attackers often exploit such flaws. Information security companies continuously monitor vulnerabilities and update security databases. Their monitoring typically includes sources such as the U.S. Government’s National Vulnerability Database (NVD), security advisories, GitHub issue trackers, and open-source projects. To create malicious code, attackers use a variety of programming languages. Some are more popular in cybercriminal circles due to their ease of use, compatibility with specific systems, and the wide availability of libraries that help solve particular problems. The Most C…  ( 6 min )

Introduction If you're encountering a frustrating build error while working with Parcel, Tailwind CSS, and PostCSS, rest assured you're not alone.

The phrase “Click here” was once a cornerstone of internet navigation. It was ubiquitous across websites, often used as a direct instruction to users: simply click a link, button, or piece of text, and something new would unfold—whether it was a download, a page redirect, or a pop-up. In the early days of the internet, this phrase was essential, helping users navigate a relatively new and confusing online landscape. But today, “Click here” is seen as a relic, a remnant of simpler times that no longer meets the standards of modern web design and user expectations. In this article, we will examine how “Click here” came to prominence, why it has lost its relevance, and the evolution of web design that has led to the adoption of more sophisticated, user-centered alternatives. The Early Days of…  ( 8 min )

"Don't… just stand there in the corner; tell me so." That was the question that paralyzed me during a client meeting. I was certain of my code, proud of my GitHub, and active on LinkedIn. But when asked to explain what differentiated me—I was stumped. Ring a bell? In the modern-day developer world, technical acumen doesn't come close. Recruiters, collaborators, and clients don't just want someone who can get it done—they want someone who fits with their culture, thinks outside the box, and contributes an extra something.

Concurrency in Go Ismile Hossain ・ May 11 #go #programming #tutorial  ( 2 min )

❓ What is Concurrency? Concurrency is the ability of a program to manage multiple tasks at once. These tasks may not run exactly at the same time, but they are managed in such a way that it feels like they are happening simultaneously. Imagine you’re cooking dinner: You put water on the stove to boil. While the water heats up, you chop vegetables. Once it’s boiling, you add pasta. While pasta cooks, you prepare the sauce. You are switching between tasks. You're not doing everything at once, but you're switching between tasks efficiently to save time. That’s concurrency: smart multitasking, not true parallelism (which involves tasks running at the exact same time on multiple CPU cores) In Go, concurrency means: Your program runs multiple tasks (functions or processes). Each concurrent ta…  ( 19 min )

When you send a message over the internet—whether it’s a cat meme, a video stream, or a DNS lookup—it’s traveling through layers of protocols. Two of the most important transport-layer protocols in this stack are TCP and UDP. While TCP gets a lot of the spotlight thanks to its reliability and widespread use in web traffic, UDP (User Datagram Protocol) is the unsung hero behind many real-time and low-latency applications. In this post, we’ll demystify what UDP is, how it works, and why developers choose it despite its nickname: the "Unreliable Datagram Protocol." UDP is one of the core protocols of the Internet Protocol (IP) suite. It was introduced in 1980 as a lightweight alternative to TCP. UDP operates on top of IP and is used to send short messages called datagrams. The key difference?…  ( 4 min )

Understanding getHashCode() in C# When working with various controls or items in C#, particularly in Windows Phone 7 (WP7), you might encounter the getHashCode() method. This method is an integral part of the object class, allowing objects to produce a hash code, which is a sequence of numbers that computably represents the object. You may wonder if this hash code can uniquely identify an item like a picture or a song on your device. In this article, we will delve into what a hash code is and how getHashCode() works within the context of C#. What is a Hash Code? A hash code is a numerical value produced by a hash function, which maps data of arbitrary size to fixed-size values, usually for efficient data retrieval. It's a way to summarize data, which means that a unique piece of data may p…  ( 5 min )

前两天的文章内容对uniapp开发鸿蒙应用做了一些详细的介绍，包括配置开发环境和项目结构目录解读，今天我们正式开始写代码。 入门新的开发语言往往从Hello World开始，Uniapp的初始化项目中已经写好了一个简单的demo，这里就不再赘述，我们直接从布局开始说起。 Uniapp的布局方式和鸿蒙原生语言ArkTs有所不同，但又颇为神似。 幽蓝君之前总结过，所有的布局方式无非只有三种，横向、竖向和层叠，其他所有的布局方式都由这三种衍生而来，Uniapp也不例外。 ArkTs中有Row()、Column()、Stack()、Flex()这几个基础的布局容器组件，更复杂一些的还有像List()、Grid()、Scroll()等等。 而在Uniapp中，基础的布局方式我们通常直接使用view容器来实现。比如我想要实现一个横向的布局，使用view容器，在view的样式中设置布局方式为row： 而到了纵向布局，只需要把布局方向设置column就行了： 接下来比较难的部分到了，对于层叠布局，ArkTs直接提供了Stack()容器，并且有对应的对齐方式可以直接设置，比较简单。但是uniapp并没有提供这种对齐方式，flex-direction中是不能直接设置层叠布局的。 我们可以使用postion属性来实现。postion的作用是设置定位方式，有static、relative、fixed、absolute集中方式，我们今天要说的是absolute。 absolute是一种绝对定位方式，是脱离了文档流、相对于父元素的绝对定位方式。 更详细一点解释就是不管它有多少同级别的组件，都不影响它以父元素左上角为原点的定位，同样的它也不影响别人，相当于悬浮在上层，使用偏移量来控制位置。比如下面这段代码： 所以如果需要层叠布局的两个容器都使用absolute定位，并且使用top、left、bottom、right来设置对齐方式，就实现了鸿蒙中的Stack()一样的功能： 这里可以使用z-index来设置谁在上一层，另外，绝对定位的父容器需要设置position: relative属性，否则子组件无法找到目标。 以上就是Uniapp开发鸿蒙的基础布局方式，感谢您的阅读。  ( 3 min )

Introduction to BlockingCollection and Memory Management In C#, the BlockingCollection class is a powerful tool for handling producer/consumer scenarios in a thread-safe way. However, when dealing with large objects that can vary in size significantly—like the ones you mentioned ranging from 10 MB to 700 MB—it's crucial to manage memory effectively to avoid OutOfMemoryExceptions. To achieve this, we need a customized collection that extends the functionality of BlockingCollection by allowing us to limit the total memory used by the items stored in it. Understanding the WeighedBlockingCollection The goal here is to create a custom collection called WeighedBlockingCollection, which will not only mimic the behavior of BlockingCollection but also impose a weight restriction on the …  ( 5 min )

TypeScript offers powerful tools that help you write clean, scalable, and type-safe code. Two of the most useful features in this toolkit are Union Types and Type Aliases. In my latest YouTube video, I break down how to use these features effectively—even if you're just getting started with TypeScript. ✅ What You'll Learn ✅ What is a Union Type in TypeScript? ✅ How to use Union Types with function parameters ✅ What is a Type Alias and how to use it ✅ How to combine Union Types and Aliases ✅ Real-world use cases and code walkthroughs ✅ Common mistakes to avoid If you've ever found yourself repeating types or making your code harder to read, Union Types let you define a variable that accepts multiple types: let id: string | number; Meanwhile, Type Aliases allow you to give a custom name to a type: type ID = string | number; function printId(id: ID) { console.log("Your ID is:", id); } Combined, they make your code more readable, reusable, and easier to maintain. type SuccessResponse = { status: "success"; data: string; }; type ErrorResponse = { status: "error"; error: string; }; type APIResponse = SuccessResponse | ErrorResponse; function handleResponse(res: APIResponse) { if (res.status === "success") { console.log(res.data); } else { console.error(res.error); } } This is a clean, scalable way to handle multiple response types from an API. I walk you through all this and more in the full tutorial on YouTube: 👉 Watch on YouTube Whether you're building a small project or working with a large team, learning how to use Union Types and Type Aliases will make your TypeScript code more maintainable and developer-friendly.

Hello everyone! It’s been another productive month in the LFX Mentorship program with the CNCF Microcks project. This month, I focused on enhancing Microcks deployments on Google Kubernetes Engine (GKE) and improving documentation for cloud-specific deployment strategies. Additionally, I had the opportunity to present my contributions during the community meeting, where I encouraged others to contribute, provide feedback, and review the documentation. Asynchronous Options on GKE I worked on improving the Microcks GKE deployment by adding support for asynchronous protocols and securing the Microcks endpoint with TLS. Enabled Kafka-based async protocols with Helm and installed Strimzi for Kafka management. Secured the endpoint using cert-manager and Let's Encrypt for automatic SSL certificate provisioning. Deploying complex systems like Microcks with external Keycloak and MongoDB can sometimes lead to roadblocks. To address this, I created a TROUBLESHOOTING.md file in the repository. This document provides a set of common issues and solutions that developers may encounter when deploying Microcks on GKE, especially when integrating with Keycloak for authentication and MongoDB for data storage. Troubleshooting Guide I developed a GUIDELINES.md document that outlines the deployment process for Microcks across multiple cloud providers. The guidelines cover setting up infrastructure, deploying Keycloak, provisioning databases, and configuring Microcks with Helm. Common Guidelines Next month, I plan to: Deploy Microcks on Azure AKS and document the process. Add a Troubleshooting Guide for Azure deployment. Month two has been an exciting journey, contributing to Microcks with improvements in deployment, security, and cloud-specific guidelines. I’m excited to continue supporting the Microcks community and look forward to the next steps! Feel free to check out my contributions on the Microcks community repository  -  feedback and contributions are always welcome! See you in the next update! 👋  ( 3 min )

JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for humans to read and write and easy for machines to parse and generate. It's one of the most widely used formats in web development, especially when working with APIs and server responses. JSON is a text-based format for representing structured data. It resembles JavaScript object syntax, but it's a string. Example JSON: { "name": "Alice", "age": 25, "isStudent": false, "skills": ["HTML", "CSS", "JavaScript"] } They look similar, but they are different: Feature JavaScript Object JSON Data Type Object String Can contain functions Yes No Comments Allowed Not allowed Quotes on keys Optional Mandatory JSON.stringify() Converts a JavaScript object into a JSON string. const user = { name: "Bob", age: 30 }; const jsonString = JSON.stringify(user); console.log(jsonString); // '{"name":"Bob","age":30}' JSON.parse() Converts a JSON string back into a JavaScript object. const jsonString = '{"name":"Bob","age":30}'; const user = JSON.parse(jsonString); console.log(user.name); // 'Bob' fetch('https://api.example.com/data') .then(response => response.json()) .then(data => { console.log(data); // Parsed JSON object }); Most APIs return JSON. Using .json() parses the response body into a JavaScript object. Forgetting to wrap keys in quotes in JSON: { name: "John" } // Invalid Correct: { "name": "John" } Using functions in JSON: JSON.stringify({ sayHi: () => "Hi" }); // sayHi will be removed JSON is used for storing and exchanging data. Use JSON.stringify() to convert objects to strings. Use JSON.parse() to convert strings to objects. It’s widely used in API communication.

Clean Architecture is a great concept. It’s meant to help you write maintainable, modular, and scalable software. But too many developers treat it like a religion. They follow it blindly, stuffing projects with unnecessary layers, abstractions, and patterns. All in the name of “clean code.” Let’s be honest, Clean Architecture is often overused, not because the ideas are bad, but because people overengineer the implementation. Here’s an example of multiplying two numbers implemented with an absurd number of patterns: // overengineered-multiplier.ts // Interface interface IMultiplier { multiply(a: number, b: number): number; } // Singleton class MultiplierService implements IMultiplier { private static instance: MultiplierService; private constructor() {} static getInstance(): Mu…  ( 5 min )

Key takeaways: Ether has rebounded from key parabolic and triangle support levels, reviving the case for a $10,000 breakout. Historical fractals and RSI recovery mirror past pre-rally setups seen in 2016 and 2020. Altseason signals and strength against rivals like SOL and XRP boost Ethereum’s potential to outperform. Ether (ETH), Ethereum’s native token, has soared over 44% in just three days to surpass $2,600 on May 11, fueling fresh speculation of a run toward $10,000 in the coming months. A mix of fractal setups as well as Ether’s potential to outperform its top-ranking rivals, Bitcoin (BTC), Solana (SOL), and XRP (XRP), are serving as some catalysts behind the five-figure price prediction. ETH's “up band” target is around $10,000 Ether’s long-term price action continues to follow …

Opinion by: Sean Li, co-founder of Magic Labs Crypto markets run 24/7. Human traders don’t. As AI agents begin to manage liquidity, optimize yield, and execute trades at all hours, they’re quickly becoming essential infrastructure for decentralized finance’s (DeFi) future. While AI agents are evolving from niche tools for quant traders into mainstream financial operators, they’re rapidly outpacing the wallets meant to secure them.  Advancements in account abstraction and smart contract wallets have emerged, but most DeFi platforms still predominately rely on externally owned account wallets that require manual approvals at every step. Early-stage programmable solutions exist but remain fragmented, costly on layer-1 networks and adopted by only a tiny fraction of users. As AI agents increas…

Ethereum’s latest network upgrade, Pectra, introduced powerful new features aimed at improving scalability and smart account functionality — but it also opened a dangerous new attack vector that could allow hackers to drain funds from user wallets using only an offchain signature. Under the Pectra upgrade, which went live on May 7 at epoch 364032, attackers can exploit a new transaction type to take control of externally owned accounts (EOAs) without requiring the user to sign an onchain transaction. Arda Usman, a Solidity smart contract auditor, confirmed to Cointelegraph that “it becomes possible for an attacker to drain an EOA’s funds using only an offchain signed message (no direct onchain transaction signed by the user).” At the center of the risk is EIP-7702, a core component of the …

Crypto services platform Nexo shared its plans to reenter the United States market on Monday, marking the eighth major crypto firm to announce such plans since US President Donald Trump took office at the start of the year. Firms like Circle, Binance and OKX are banking on favorable regulatory clarity in 2025 to herald their US expansion. Bills like the STABLE Act and the GENIUS Act are advancing in Congress, which, if implemented, will lay the groundwork for swift success. Trump and his family are actively involved in some of these planned expansions. Nexo’s recent announcement was backed by Donald Trump Jr., who said, “We see the opportunity for the financial sector and want to ensure we bring that back to the US.” Amid concerns of conflicts of interest and blatant token shilling by the …

Worldcoin’s latest hardware, the Orb Mini, aimed at enabling portable human verification, has been met with ridicule across Crypto Twitter. Launched with the slogan “It goes where you go,” the device has instead triggered dystopian comparisons and widespread mockery for its unsettling implications and unclear use case. “The thing about humans is they can tell when a human is in front of them,” Alicia Katz from decentralized finance (DeFi) lending platform Euler Finance wrote on X. “When something is slightly off, they can experience the uncanny valley, an uncomfortable feeling similar to when your date tries to scan your eyeball,” she added. Another user quipped, “Is this so you can register your friends?” likening the device to a sci-fi prop rather than a serious identity solution. Source…

Hackers drained over $2.15 million from Mobius Token ($MBU) smart contracts on the BNB Chain in a targeted exploit detected early May 11, according to security firm Cyvers Alerts. The attacker deployed the contract from address 0xb32a53... at 07:31:38 UTC and initiated the exploit at 07:33:56 UTC, draining funds from the victim wallet 0xb5252f... Cyvers confirmed to Cointelegraph that the attacker used contract 0x631adf... to execute a series of malicious transactions. The smart contract drained 28.5 million MBU tokens and converted them into stablecoins, resulting in a net loss of $2,152,219.99 for the victim. In total, the attacker stole 28.5 million MBU tokens and converted them to $2.15 million worth of USDT. Cyvers labeled the exploit as “critical” and noted the attacker’s use of suspicious contract code and abnormal transaction patterns. The attacker’s wallet remains active and has retained the stolen funds as of publication. Mobius Token’s team has not yet released an official statement. “Two minutes prior to the exploit, our system identified a deployment of a malicious smart contract that eventually targeted the Mobius Token smart contracts,” Cyvers wrote on X.

Altcoin markets are flashing early signs of a breakout, with several analysts calling for a potential surge over the next few months. Crypto commentator Mister Crypto predicts the next 3 to 6 months could be “life-changing,” suggesting daily gains of up to 40% may soon become the norm. In a May 11 post on X, he pointed to a chart from BlockchainCenter.net that shows whether the crypto market favors Bitcoin (BTC) or altcoins. When the index is below 25, it’s considered “Bitcoin Season,” meaning Bitcoin is outperforming most altcoins. When it’s above 75, it’s “Altcoin Season,” meaning altcoins are doing better than Bitcoin. Currently, the chart shows a breakout from a downward trend just below the 29 mark, suggesting a possible shift away from Bitcoin dominance. This breakout hints that altc…

Coinbase CEO Brian Armstrong said his company had considered adopting a Bitcoin investment playbook like Michael Saylor’s Strategy on multiple occasions, but decided against it each time out of fear that it would kill the firm’s crypto exchange, Bloomberg reported. “There were definitely moments over the last 12 years where we thought, man, should we put 80% of our balance sheet into crypto — into Bitcoin specifically,” Armstrong revealed to Bloomberg in a May 9 video call. Armstrong said the Bitcoin (BTC) strategy could have risked the company’s cash position and potentially killed the crypto exchange. “We made a conscious choice about risk,” he added. Coinbase Chief Financial Officer Alesia Haas, who also attended the video call, added that the firm didn’t want to be seen as directly com…

Abstract Introduction The conventional model of web application development separates frontend and backend responsibilities into different teams, skillsets, and codebases. Frontend developers manage UI and client-side logic, while backend developers handle server-side processing, API creation, data storage, and security enforcement. However, this division can lead to longer development cycles, coordination challenges, and duplicated logic across layers. A new paradigm is emerging—one in which frontend developers can declaratively define backend logic using frontend tools and syntax. This shift is enabled by modern platforms that offer serverless scalability, secure permission management, and efficient request/response handling under the hood. This approach doesn't eliminate the need for ba…  ( 5 min )

Introduction to UDF and Vector UDF in Spark 3 In Spark 3, the advent of vectorized UDFs (User Defined Functions) has created a significant advancement in how operations on DataFrames can be efficiently executed. Understanding the differences between traditional UDFs and the newer vectorized UDFs is crucial for optimizing performance in big data processing. What are User Defined Functions (UDFs)? Traditional UDFs User Defined Functions, commonly referred to as UDFs, are functions written by users to extend the functionality of Spark. They allow you to perform custom operations on DataFrames and Datasets. For example, if you want to apply a complex transformation that is not available out-of-the-box in Spark, a UDF can be created in languages like Scala or Python. How Traditional UDFs Work T…  ( 5 min )

Introduction When working with Entity Framework Core (EF Core) in C#, managing relationships between entities is crucial. In this scenario, we have a case where a department can have multiple users, and when a user is assigned a new department, we need to ensure the previous department is deleted if it has no users left. This is a common requirement in applications that handle organizational structures. Why the Department Query Might Not Reflect Updates In your situation, you are attempting to update a user's department and then immediately check if the previous department has users left. You notice that even though the update reflects in the database, the department load returns stale data. This issue can arise due to EF Core’s change tracking behavior and how it interacts with the databa…  ( 5 min )

Libuv describes itself as a multi-platform support library with a focus on asynchronous I/O. It is widely used in many web servers (e.g., Kestrel) and runtimes such as Node.js and Python (via uvloop). As of Zig 0.14.0, there is no native async I/O, so you must work directly with threads or create your own async API using OS primitives like epoll or kqueue. In many cases, you would likely choose a cross-platform library rather than implementing your own async API. That’s where using libuv, libevent, or libxev (written in Zig) becomes useful. This guide will show you how to use libuv from your Zig project. I’ll start with a basic Zig project to demonstrate how this works. It will be a simple app that runs some timers. We’re going to use the package from github.com/allyourcodebase/libuv to bu…  ( 5 min )

An open-source project called Deep-Live-Cam is gaining traction on GitHub — and for good reason. With just a single still image, it can mimic anyone’s face in a live video call. In real-time. Running locally. No cloud required. The implication is clear: you can no longer trust a video call at face value. So here’s the question: how do we verify identity in a world where faces can be forged on demand? While many react with fear or disbelief, I see only one viable answer: digital signatures. For years, I’ve been saying: we should encrypt everything — files, messages, infrastructure. But now, that’s not enough. We need to start signing everything. Digital signatures ensure authenticity. They prove that something really came from who claims to have sent it and hasn’t been tampered with. We already sign emails, source code, and software packages. Why not apply the same principle to real-time streams? Imagine a video call cryptographically signed with the speaker’s GPG key. Even if the face looks convincing, if the signature doesn’t verify, you know something’s off. I sign every HTML page on my personal website with my GPG key. Not because I’m paranoid — but because I believe security should be a mindset. Don’t trust. Verify.  ( 3 min )

If you're learning C# or .NET development, you might encounter this frustrating error: One or more errors were encountered while creating project ConsoleApp3. The generated project content may be incomplete. The SDK 'Microsoft.NET.Sdk' specified could not be found. I faced exactly this issue during my early days learning C#. After multiple attempts, I finally found a solution that worked reliably for me: The root cause appears to be that the official .NET SDK installer sometimes doesn't correctly set up the SDK on your system. Even after installation, the command dotnet --list-sdks might return an empty list, which indicates the SDK isn't properly recognized by your system. Here's what worked for me: Download the Binaries Manually: Go to the official .NET SDK downloads page. Instead of downloading the installer, choose the "Binaries" option. This will give you a .zip file containing the SDK files directly. Extract and Copy Files: Extract the downloaded .zip file to a temporary location. Replace SDK Contents: Navigate to: C:\Program Files (x86)\dotnet\ Delete or back up existing contents, then paste the newly extracted SDK binaries into this folder. Verify Installation: Open a new Command Prompt or PowerShell window and run: dotnet --info You should now see details about the SDK and runtime versions installed. This solution manually ensures that the SDK files are correctly placed and recognised by your system, bypassing the potential issues caused by the automated installer. If you're still experiencing issues after following these steps, consider checking your environment variables to ensure C:\Program Files (x86)\dotnet\ is correctly listed in your system PATH. I hope this guide helps anyone stuck with this annoying issue! If you find additional solutions or improvements, please share them—I'm still learning and would love to hear from you.  ( 3 min )

gRPC (Google Remote Procedure Call) is a high-performance, open-source framework for making remote procedure calls. Unlike traditional REST APIs that use HTTP/1.1 and JSON, gRPC leverages HTTP/2 and Protocol Buffers for more efficient communication between distributed systems. This modern approach offers significant advantages in terms of performance, type safety, and code generation capabilities. When working with gRPC, you need to understand the fundamental components and workflow that differentiate it from other API communication methods. The process begins with defining your service interface using Protocol Buffers (protobuf) in a proto file, which serves as a contract between client and server. This definition is then compiled into language-specific code that handles all the underlyin…  ( 5 min )

Introduction Have you ever faced an unexpected behavior in your Bash scripts, particularly regarding loops? In this article, we will delve into a common issue with the continue statement in Bash, as illustrated by your provided script. You're correct in observing that the continue statement should skip the remaining commands in the loop and jump to the next iteration. So, why isn’t it working as expected in your case? Understanding the Issue The primary reason the continue statement may not be functioning as you expected lies in the structure of your loop and the way Bash interprets commands. A common mistake is how command substitutions and pipes are handled in Bash scripts. When you use a pipe (|), the commands are run in separate subshells. This means the continue statement is scoped to…  ( 4 min )

As software engineers, our job isn't just writing features or fixing bugs. We're responsible for improving the processes around software and help teams move faster, safer, and more consistently. That means asking questions like: Can we reduce repetitive tasks? Can we encode best practices so new team members don't guess? Can we lower the mental load of starting new features? For Angular projects, Schematics is one of the best tools to operationalize these improvements. It lets you automate architecture, encode standards, and enforce patterns. A schematic in Angular is a set of instructions that tells the Angular CLI how to generate or transform code. Think of it as a script that can: Create new files using templates. Update existing code (e.g. add a component to a module). Enforce consiste…  ( 4 min )

Hi devs — I recently launched a platform called aimodeling.me, and I’d love to share what it does, how it works, and why I built it. In short, it lets you create a realistic AI model of yourself — your own "digital twin" — from just a few selfies. After that, you can generate endless photorealistic images of you in any scenario, outfit, or setting you can describe. We’re all used to AI image generators now, but most of them produce generic faces or imaginary people. I thought: what if we flipped that? What if you could put yourself in those scenes? Professional photoshoots are expensive, awkward, and static. I wanted a way to generate high-quality, personalized photos for myself (for social media, bios, content creation, etc.) without constantly needing to step in front of a camera. So I b…  ( 4 min )

Working in Japan under the constraints of a work visa means there’s really not much you can do besides your day job. About the only other option is saving money and investing through NISA... Even if your company allows side jobs, you still need to apply for “Permission to Engage in Activity Other Than That Permitted Under the Status of Residence,” and possibly register and communicate with the authorities. Just thinking about all that paperwork makes me not want to bother. After all, the main goal is to build a life where I can live long-term in a place I truly want to be — for me, that’s Japan. So in reality, my daily life basically revolves around working and studying to prepare for a career move. I won’t deny that this kind of routine gets a bit dull over time. I just want a little more freedom, especially since both language learning and job hunting take so much time. Anyway, I need to hit my goal as soon as possible so I can finally enjoy the freedom I want in Japan!  ( 3 min )

This blog is for those, who want to start their first full stack development project but not have enough idea about how to start. I will try to cover some of the things that you should follow for make your first project journey more smooth. Folder Structure: The first thing you might face difficulties is creating and understand the folder structure. It may vary by project to project, but their are some common concept like creating 2 separate folder, one for frontend and other one is for backend. Inside each folder you will have multiple folders. For backend you will have folders like models, services, api endpoints etc (based on your requirements) . And for frontend, you will have src folder inside which you will find components, assets, pages, api, utils etc folders (if you are using React). fullstack-project/ Make sure you must write code as clean as possible. It is a good practice. You should right the logics more efficient way. You can also create a folder for a particular module and inside that you can create multiple files so that anyone can easily find the code written for a specific purpose. It will reduce cognitive complexity. Another thing you should remember that don't make a function so large with so much logics in a single function, rather use multiple functions, each for a particular logic and use them in that function. Before writing any routes, you should always first do some floor planning like how this routes is going to use, how many times this routes will be called. It is completely necessary when you are going to deploying the project into the server. Because the more api needs to call from backend, the more it will take time to load and resulting the website slow. Wish a happy journey for your first project 😄 and share if you find this post helpful.  ( 4 min )

Have you ever felt like you're fighting with your own APIs? As a backend developer, I sure did... until I learned to stop debugging through the frontend and start talking directly to my APIs instead. Last month, I was building a backend for a mocktail ordering system. Everything was in place: // Our beautiful API endpoints app.post('/api/auth/register', registerUser); app.get('/api/auth/logout', logoutUser); app.get('/api/products', getProducts); app.post('/api/events', createEvent); app.post('/api/orders', createOrder); app.get('/api/invoices', getInvoices); app.get('/api/payments/history', getPaymentHistory); app.delete('/api/users/:id', deleteUser); Then the moment of truth came: testing the "Delete Account" feature. Click... and nothing happened. No error, no confirmation, nothing. My…  ( 5 min )

You can read the intro here: Let’s say you join a new team and find this in one of the core API controllers: [HttpPost("updateOrder")] public async Task UpdateOrder([FromBody] OrderDto order) { var updatedOrder = await _orderService.Update(order); return Ok(updatedOrder); } At first glance, it seems reasonable. It compiles. It works. It even passes QA. But if this looks fine to you — keep reading. This kind of code is deceptively simple. In fact, it’s a perfect example of how bad design doesn’t look broken, until it is. Under the surface, this endpoint is full of subtle flaws that will confuse consumers, pollute your Swagger docs, and slow your team down over time.

Most programmers will agree that state management is a pain (in the head). Which is why they shy away from it at every opportunity. Languages, functional or OOP, make no difference - if state is only ever passed around to and from the database, it's all practically stateless in my book. In the industry-accepted programming model (clean model, layered model, hexagonal model) state management (database I/O) is on the outer layer - why? Oh, because you don't actually operate on entities that you store, you operate on transient entities derived from them. This abstraction is necessary, because in most modern languages state is carried by objects - and you can't store objects, only things derived from them. Be it rows in tables, or at least whole aggregates in NoSQL DBs. Actual object state can…  ( 4 min )

I've been developing PHP applications for over 15 years now, working with various PHP frameworks. Throughout this journey, I've witnessed many projects that began as monoliths eventually need to evolve into microservices. That's when interesting architectural challenges emerge. While I'd successfully used RoadRunner (RR) with Spiral and Symfony before, I wanted to bring these same capabilities to my Laravel projects. Yes, Laravel Octane does provide RR integration but only for HTTP. I needed the full ecosystem of plugins that make RR truly powerful for distributed systems.

At M47 Labs, we work on many AI and cloud-native projects where secret management becomes complex — especially across environments and CI/CD pipelines. We're big fans of AWS SSM for storing configuration and secrets securely, but syncing them into .env files can be painful and repetitive. To solve this in a cleaner and more reliable way, I built a CLI tool: 👉 Envilder on GitHub Envilder reads a mapping file that links environment variable names to AWS SSM parameter paths. .env file. Your param-map.json might look like this: { "DB_HOST": "/my-app/dev/DB_HOST", "DB_PASSWORD": "/my-app/dev/DB_PASSWORD" } Run: envilder --map=param-map.json --envfile=.env And you get: DB_HOST=mydb.cluster-xyz.rds.amazonaws.com DB_PASSWORD=supersecret You can also use different AWS CLI profiles: AWS_PROFILE=staging envilder --map=param-map.json --envfile=.env This small tool makes a big difference when: 🧑‍💻 Onboarding new team members: no more “what’s the DB password?” 🔄 Keeping environments in sync: any change in SSM is reflected across the team ⚙️ CI/CD pipelines always up-to-date: e.g. GitHub Actions, CodeBuild, GitLab 🧼 Centralized configuration: avoid duplication and keep secrets in one secure place 🧭 Supports multiple AWS profiles: ideal for multi-account or multi-env setups Works with SecureString and plain parameters CLI-first, fast, and script-friendly Compatible with any CI system Supports static values and fallbacks AWS profile support (AWS_PROFILE) npm install -g envilder Or: envilder --map=param-map.json --envfile=.env --profile=aws-account It’s still an early-stage project, but already helpful in several real-world teams.

Stop Guessing: Understand JavaScript Equality the Right Way When you start working with JavaScript, one of the first things you notice is how flexible it feels. You can assign different types of values to the same variable and JavaScript won’t complain. This flexibility is great—but it can also lead to unexpected bugs, especially when you're comparing values or checking if something is "true" or "false." Let’s break down some of these concepts in a beginner-friendly way so you can write safer and more predictable JavaScript code. In JavaScript, you don’t need to declare the type of a variable. For example: let x = 5; // x is a number x = "hello"; // now x is a string x = true; // now x is a boolean This is called loose typing—a variable can hold any type of data, and JavaS…  ( 6 min )

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Crushing the Command Line Some AI-powered coding assistants already support code reviews, but most of them tend to review an entire workspace or just the currently open file. In real-world scenarios though, code reviews are often based on pull requests—where we only need to review changes between two branches, not the whole project. For example, reviewing just the differences between a hotfix branch and main. That got me thinking: wouldn’t it be great if an AI coding assistant could handle that kind of focused review? At least as a first layer—giving us a detailed AI-generated review of the changes before we jump in manually. That way, human reviewers can just focus on refining things further instead of starting from scratch. One of Amazon Q Developer’s cool features is its CLI and MCP (Model Context Protocol) support. So I thought: why not use Amazon Q CLI to compare two branches—say, hotfix and main—and then have it go through the changed files one by one, review them, and finally compile the feedback into a single file using MCP as well? That way, whoever’s reviewing the PR can read the AI’s review first before doing their manual checks. Code Repository Code Review with Amazon Q Developer CLI I used Amazon Q Developer as the first layer of code review—comparing one branch to another, like from hotfix to main. This helps make the review process smoother, more effective, and scalable—especially when combined with a follow-up manual review. What makes it even more exciting is that Amazon Q Developer can both generate code and review it too. Pretty handy, right?  ( 4 min )

-- Loose Equality allows different kinds to become an equal kind. I've been feeling, blogposts treat loose equality in JavaScript as a kind of black magic because people do not master it. It isn't supposed to be esoteric magic. I am not involved in browser development but I conducted my tests with Firefox and Chrome and I read the MDN pages. You can check the examples. I say, make full potential of Javascript's capabilities, intentionally and knowingly. It can save us from some coding overhead, even when the original definition is sometimes flawed. The loose equality can make code more concise… This means, if you know the types of the operands. Therefore, the loose equality is particularly useful with TypeScript, because it can show you the types of expressions. True, even TypeScript lack…  ( 8 min )

In Part 1, we used Kubernetes Ingress to route traffic to two Go-based microservices based on specific paths. In this second part, we’ll explore advanced Ingress features. In this part, we’ll build and deploy two updated Go-based services (API and Web) in the ~/k8s-learning/ingress/ingress-different-route directory.

So this week, I tried to share what I’m building on Reddit. Two posts. Two different subreddits. Both were removed instantly by Reddit’s filters. No explanation. No mod feedback. Just gone. What were the posts about? I’m building a solo project called KindredCircl — a social platform focused on belonging, privacy, and connection. No ads. No rage-bait. No surveillance. Both posts were written thoughtfully. No spam. No “buy this.” Just honesty, tech stack, and a link to a longer write-up on Dev.to. But apparently, Reddit’s automation saw all that and said: nope. Reddit is supposed to be where indie hackers hang out. Where devs build in public. Where creators share early work and get support. But what I’m realizing is: if your post doesn’t match the format the filter expects, or if you use certain words (like support, link, or solo founder), you might just get silenced. Not because of what you said — but because a bot decided you were promotional by default. I’m still building. I’m still sharing. But I’m reminded how important it is to build spaces where authentic effort isn’t treated like spam. KindredCircl is meant to be one of those spaces. And yes — it still exists, even if Reddit didn’t want to hear about it this week. If you’ve had posts removed without explanation, or felt like you’re shouting into the void, I’d love to hear your story too. Let’s be loud for each other — since these platforms clearly won’t do it for us.  ( 3 min )

A few days ago, I stumbled across an interesting blog post by Solusipse about hiding images in sound—more specifically, encoding them into the spectrogram of an audio file. It reminded me of old-school tech like dial-up modems and the ZX Spectrum, but with a modern twist. Naturally, I had to try it. Solusipse provides a Python script, spectrology.py, that takes an image and converts it into an audio waveform whose spectrogram visually resembles the image. I cloned the repo, followed the README, and ran the script, hoping for a cool output. But things weren’t so smooth. The script hit an error out of the gate.

It all started innocently enough. Back in 2009, I just wanted to port Earcut to Flash for a mini-game I was working on. And honestly? It worked — for a while. But over time, I realized that simple solutions tend to fall apart the moment you try to push them to their limits. That’s when I dove into the theory - digging through research papers, YouTube tutorials, and whatever else I could find. One of the most helpful resources was a book by A.V. Skvortsov. Eventually, I landed on the classic approach: decomposing a polygon into monotone pieces. It seemed obvious. And oh - I hit every possible wall while trying to make it work. The first big insight? Replace float with int. That alone got me almost there. But the algorithm was still fragile. Really fragile. Self-intersections, collinear edge…  ( 7 min )

Docker isn’t just about running containers. It’s about understanding how systems work, why things break, and what to do next. Most tutorials give you commands to copy paste. This guide gives you projects to learn from, backed by theory and real-world context. By the end, I’ll share a secret most Docker experts won’t tell you a way to master it faster. Let’s start. Build a Multi-Container App with Docker Compose Modern apps rely on multiple services (like a web server, API, and database). Docker Compose orchestrates these services, handling networking and dependencies. Without it, you’d manually start each container and connect them a recipe for errors.

✍️ Introduction Throughout my experience working with clients from domains like healthcare, insurance, and legal, I often found myself curious about how certain backend document workflows functioned, especially in healthcare. While supporting these systems, I’d often get paged for incidents related to PDF pipelines: upload failures, script errors, or extraction gaps. At that stage, like many in support roles, we’re limited to handling outcomes rather than building or understanding the full solution. Over time, as we gain more experience, build trust, and make people feel confident in our abilities, we gradually get the opportunity to be part of architecture discussions and solution design conversations. But that curiosity about how these pipelines actually work — from PDF upload to raw t…  ( 5 min )

AI agents are no longer science fiction. We're moving fast toward a world where intelligent agents assist in everything from customer service and infrastructure orchestration to dev workflows and automated research. These agents aren’t monoliths—they're modular, specialized, and increasingly autonomous.

A constructor function is a special type of function used to create and initialize objects in programming, particularly in object-oriented languages like JavaScript. Think of it as a blueprint or factory for making many similar objects. Imagine you're managing a car manufacturing company. Every car you build shares the same structure—engine, wheels, color, and brand—but each one has its own values. Instead of manually building each car from scratch, you use a car-making machine (constructor function). You input values like color, brand, and engine size, and the machine builds the car for you. function Car(brand, color, engineSize) { this.brand = brand; this.color = color; this.engineSize = engineSize; } This is the constructor function.

In today's rapidly changing programming world, Rust and Zig are the hottest topics. Both modern, low-level programming languages exist mainly to address shortcomings in older systems programming languages like C and C++. But which one would you choose to learn in 2025? Is Zig a competitor to Rust, or does it remain the reigning champion? We will discuss their pros and cons and their best use cases. The Rise of a New Competitor But now, there comes a new competitor: Zig. Lightweight and flexible, it's not going unrecognized by the low-level developers with its focus on manual memory management, compile-time safety, and minimal run-time overhead. With this adoption trend, that question arises among many of how true this is: ''Is Zig a real competitor to Rust?'' Hence, in the following article, we shall compare Rust and Zig, note significant differences, and possibly help you decide on which of the two you are planning to learn in 2025. Why is Rust So Popular? 1. Memory Safety Without a Garbage Collector 2. Fearless Concurrency 3. Performance on a Par With C and C++ Rust provides zero-cost abstractions that allow a high level of expressiveness in writing programs while incurring little or no run-time overhead. In many cases, Rust is as fast as or faster than C/C++. 4. A Thriving Ecosystem and Strong Tooling Rust Uses and Applications For massively scalable applications, Rust fits the bill. The flip side of such scalability would certainly be a lot of complexity, and this is where Zig fills the void. The Minimalist Challenger: Zig Unlike Rust's expensive and stringent powers with sections for systems programming, Zig is strictly minimalist and performance-optimized with no specific automated memory management.

I’m building a project using Next.js (latest version) with Tailwind CSS and deploying it to Vercel. The issue is: all design changes (layout structure, visual style updates, etc.) show up perfectly in local development, but they don’t appear at all on the production URL after deployment. Things I’ve tried: git push to main runs without errors. Vercel deployment shows status as “Ready” with no build errors. Forced browser refresh (Ctrl+Shift+R), cleared cache, used incognito mode. Tested on multiple browsers and devices. What could prevent design changes from being reflected in production? I’d appreciate any advice or suggestions. I’ve repeated the steps multiple times and still can’t get the updated design to show live.  ( 3 min )

In the digital age where apps talk to servers, systems talk to each other, and devices sync data across continents, JSON stands tall as the standard language of communication. Simple in form but powerful in function, JSON is a foundational technology in software development, used across web, mobile, IoT, AI, databases, and cloud platforms. Let’s break down JSON from theory to real-world practice, with examples and project-level applications. JSON (JavaScript Object Notation) is a lightweight text-based format for representing structured data. Despite its name, JSON is language-agnostic, and supported natively or via libraries in virtually all programming languages.

Cloud computing isn't simply a catchphrase in today's digitally first society; it's the foundation of contemporary company operations. The cloud makes speed, size, and cost-effectiveness possible for everyone from start-ups releasing mobile apps to multinational corporations overseeing operations worldwide. However, "the cloud" isn't a universally applicable answer. Different kinds of cloud services are available, depending on what you're building and how much control you desire. Let's dissect them. 1. Infrastructure as a Service (IaaS) What User Manages: What the Provider Manages: Use Cases: Examples: Ideal for: Developers and system administrators who want flexibility without managing hardware. 2. Platform as a Service (PaaS): What User Manages: What the Provider Manages: Use Cases: Examples: Ideal for: Developers who want to build applications quickly without worrying about backend setup. 3. Software as a Service(SaaS): What User manages: What the Provider Manages: Use Cases: Examples: Ideal for: End-users or businesses who want to use powerful software without installing or maintaining it. What Should You Pick? Choose Infrastructure as a Service (IaaS) if you require total control over your environment. Select PaaS if you wish to concentrate just on development. SaaS is your friend if all you need to do is use an app to get started quickly.  ( 4 min )

Understanding the Issue of Missing URL Parameter in FastAPI When using a Next.js frontend to send data to a FastAPI backend, it's important to ensure that all parameters, including files and URLs, are properly formatted and sent in the FormData. In your case, while the username and files are being received correctly by the FastAPI endpoint, the urls parameter is showing up as None, which can be quite perplexing. Let’s dive into the potential reasons why this is happening and how to resolve it. Reasons Why the URLs Parameter Might be None Incorrect FormData Structure: One common reason for receiving None in the FastAPI backend for the urls parameter could be due to the way the data is appended to the FormData in the Next.js code.

Legal tech is booming, but building for the legal industry comes with hidden technical, ethical, and compliance challenges..here’s what every dev should understand before jumping in. So you want to build the next AI tool that revolutionizes law? Great!!legal professionals need better, faster tools. But before you start coding your first legal document parser or compliance bot, there are real-world landmines to avoid. Legal data is often highly sensitive and subject to strict confidentiality rules (think attorney–client privilege or court-sealed documents). Scraping, storing, or even training on this kind of data without safeguards could expose you and your users to legal risk. Also, when your AI outputs a compliance decision (e.g., GDPR audit findings or AML flags), you're not just providing a "suggestion", you may be influencing legal liability. Many jurisdictions require explainability, auditability, and even human-in-the-loop systems. Legal language is dense, full of nuance, and jurisdiction-dependent. Two identical phrases may have opposite meanings depending on where and how they appear. Of course, you know there are already APIs and frameworks built for legal applications. Don’t reinvent the wheel. Legal professionals are risk-averse by design. They value clarity, documentation, and accuracy over speed. Your app’s UX must reflect that. If they can’t trust it, they won’t use it, no matter how smart it is. Are you building legal tech tools? What challenges have you run into? Drop a comment or connect—let’s push the future of legal AI forward, together.  ( 3 min )

昨天的文章介绍了使用uniapp跨平台鸿蒙应用时如何配置开发环境和运行调试项目,今天介绍一下uniapp项目目录的结构。 上面的两个文件夹pages中存放的是项目的页面，static则是存放静态资源的文件。 继续往下面看，App.vue文件打开可以看到它里面存放了项目的生命周期函数，比如项目启动、项目退出等等。 index.html相当于项目的根页面，它虽然也属于页面，但是在uniapp中通常是不需要大家修改的，因为可以看到里面有一个id是app的容器，我们在项目中写的所有代码最终都会注入到这个容器中。 Main.js是整个项目的核心入口文件，负责初始化Vue实例和全局配置 Manifest.json中存放了项目的各种配置文件，项目的名称、版本、描述、各个平台的的运行配置都在这里。 Pages.json中存放了项目中所有的页面路径和全局样式，尝试在globalStyle中的样式做一些修改，项目的全局样式就会被改变。而当新建了一个页面时，也会在这里自动注册。 最后的uni.scss文件，打开可以看到它已经给出了解释，这里是uni-app内置的常用样式变量。 以上就是uniapp项目初始化后的项目结构，还没结束，当我们运行项目后，还会新增unpackage目录，打开可以看一下是不是很熟悉，编译器把uniapp项目编译成了鸿蒙项目，这就是跨平台开发的运行原理。 以上就是对uniapp项目结构的详细解读。经历了两天的项目环境搭建和介绍，接下来的教程我们会进入到正式的跨平台开发编码环节，欢迎您持续关注。  ( 2 min )

I've embarked on a project that, although simple, has been a challenge. I've built my personal website, resume, and code visible on GitHub. This has been a bit of a challenge, because I knew my code would be visible and analyzed by recruiters. Still, I did it with love and enjoyed the experience. With it, I've had to be a software architect, content creator, project manager, developer, and SEO. Along the way, I've learned and grown. I've seen things I want to take to other projects, and the importance of following the principles of clean code, design patterns, and an architecture that's easy to scale. This project is built with Angular version 19. I use standalone components, computed properties, and effects, as well as rxResource and new features of the framework. For the UI, I used Angular Material, but minimally. The design is simple, designed so that people with visual impairments can use it without problems, balancing color contrast and good visual results. The result is my personal website, which I've been building little by little, and which I'm now sharing with you at www.antonioubedamontero.com.

POS testing involves testing the POS application to ensure it’s ready for market use. The testing environment mimics the real-world retail scenario, and the tester will take the POS system through multiple use cases to see how it holds up to day-to-day usage. Typically, POS software testing takes place at two levels—how it runs transactions at the front end and how the systems work at the enterprise back end. There are three main parts in a POS system architecture: POS terminal: This is the place from which the POS system runs all its functions. Server: This stores all information about the retail unit, including inventory details, product prices, applicable discounts, and more. Any query generated at the main terminal gets transmitted to the server. Processing unit: This processes the req…  ( 7 min )

One of Zig’s most powerful features is its ability to run code at compile time. This enables code generation, validation, and optimizations that would be much harder (or impossible) in many other languages. In this tutorial, we’ll walk through practical examples of Zig's compile-time programming and how you can use it effectively. You can run code at compile time using comptime: const std = @import("std"); const num = comptime calculate(); fn calculate() usize { std.debug.print("Evaluating at compile time\n", .{}); return 42; } Here, calculate() is run at compile time, and num becomes a constant value. comptime Parameters Zig lets you write generic functions and types using comptime parameters: fn identity(comptime T: type, value: T) T { return value; } const result = ide…  ( 4 min )

Zig’s build system might look unfamiliar at first, but it's actually one of its greatest strengths. By using Zig itself as the configuration language, build.zig gives you full programmatic control over compiling, linking, testing, and more — without external tools or DSLs. build.zig? Every Zig project with multiple files or custom build steps uses a build.zig script. This script defines how to build your application using Zig's std.Build API. build.zig Example Here’s a simple build script for a Zig executable: const std = @import("std"); pub fn build(b: *std.Build) void { const target = b.standardTargetOptions(.{}); const mode = b.standardReleaseOptions(); const exe = b.addExecutable(.{ .name = "hello", .root_source_file = .{ .path = "src/main.zig" }, …  ( 4 min )

Introduction If you're new to Dart and want to manage data efficiently, using a class to store instances in a map is a great approach. In your case, you're trying to maintain a persistent map that holds instances of myCar, but you're encountering an issue where the map is reset every time addInfoToMap() is called. Let's explore why this is happening and how to fix it. Why is myMapOfCars Being Reinitialized? The main reason myMapOfCars is reinitialized each time is that it's defined as an instance variable (implicitly associated with each instance of the myCar class) rather than as a static variable that belongs to the class itself. Each time you create a new instance of myCar, a new myMapOfCars is created, which is why it appears empty when you call addInfoToMap(). Solution to Persist Data…  ( 4 min )

Enums and error sets in Zig offer powerful ways to model states and failures with clarity and precision. In this tutorial, we’ll cover the basics, then walk through real-world uses of both types — and how they play nicely together. Enums let you define a type with named values: const Direction = enum { North, South, East, West, }; You use them like this: const dir = Direction.North; Zig will guarantee at compile time that dir is one of the defined directions. Zig encourages exhaustive switching — the compiler checks for missing cases: switch (dir) { Direction.North => std.debug.print("Going up\n", .{}), Direction.South => std.debug.print("Going down\n", .{}), Direction.East => std.debug.print("Going right\n", .{}), Direction.West => std.debug.p…  ( 4 min )

Opinion by: Kevin Rusher, founder of RAAC It’s a volatile world out there. This year, we’ve seen stocks take a wild ride as gold has pumped and crypto has been caught somewhere in the middle. Investors have dumped risk assets and scrambled for safe havens. Gold is leading the charge. While gold is safe, it is not very hard-working. Unlike cash and treasuries, the yellow metal does not generate income. Now, more than ever, investors need to be able to earn yield on gold — particularly in the decentralized finance (DeFi) sector. The only way to make money from gold is to buy low and sell high. Most investors don’t tend to buy gold like this. That’s for good reason — over the long term, gold’s performance is typically consistent, if not without a few peaks and troughs here and there, as we h…

Key takeaways: Ether is set for its best weekly gain since May 2021. Ethereum’s Pectra upgrade, mega-whale accumulation, and a major short squeeze fuel the rally. Technical patterns suggest a potential 40% rally toward $3,400 as ETH bounces off key support. Ether (ETH) is on course to record its best weekly performance since May 2021, having risen by over 37.50% in the week ending May 11, including 10.30% gains in the last 24 hours. US tariff updates, Pectra upgrade boost Ethereum The announcement of a new trade agreement between the US and the UK on May 8 and the initiation of US-China trade talks afterward have bolstered upside sentiment in Ether and the broader crypto market. Additionally, Ether benefits from its Pectra upgrade on May 7, which introduced key improvements like higher…

After 4chan was hacked on April 14 and vast troves of user and moderator data were leaked online, the controversial website quickly went down, and many believed it would never recover. However, less than two weeks later, the imageboard was back online, defiant as ever. “4chan is back,” an official blog post proclaimed. “No other website can replace it, or this community. No matter how hard it is, we are not giving up.” The imageboard has left its mark on the world in many consequential ways, birthing countless memes and conspiracy theories, serving as a platform for political movements ranging from the alt-right to Anonymous, and acting as a dumping ground for leaks and hacks of all sorts.  Crypto is no exception, with 4chan also a historically influential gathering place to share altcoin …

On April 29, UK Finance Minister Rachel Reeves unveiled plans for a “comprehensive regulatory regime” aimed at making the country a global leader in digital assets. Under the proposed rules, crypto exchanges, dealers, and agents will be regulated similarly to traditional financial firms, with requirements for transparency, consumer protection, and operational resilience, the UK Treasury said in a statement released following Reeves’ remarks. Per the statement, the Financial Services and Markets Act 2000 (Cryptoassets) Order 2025 introduces six new regulated activities, including crypto trading, custody, and staking. Rather than opting for a light-touch regime similar to the EU’s Markets in Crypto-Assets (MiCA), the UK is applying the full weight of securities regulation to crypto, accordin…

Hong Kong-based fintech firm RedotPay has reportedly launched its cryptocurrency-enabled payment cards in South Korea, positioning itself as a potential disruptor in a market dominated by traditional credit card firms and mobile payment services. The company’s crypto debit cards—both physical and virtual—are now accepted at all Korean merchants that support Visa, according to a May 9 report by The Korea Economic Daily. The move marks RedotPay’s latest step in global expansion, following its earlier partnership with Visa and BIN sponsor StraitsX in February 2025 to enhance cross-border crypto payment capabilities. RedotPay, founded in 2023, has rapidly scaled since the soft launch of its crypto card program in late 2024. It now serves more than 4 million users worldwide. In South Korea, use…

Robert Kiyosaki, businessman and best-selling author of Rich Dad Poor Dad, is once again sounding the alarm on the dangers of centralized monetary policy — urging his followers to abandon what he calls “fake money” and adopt alternatives like Bitcoin, gold, and silver. In a May 10 post on X, Kiyosaki backed a hardline stance against central banking systems, particularly the Federal Reserve, while quoting former US Congressman Ron Paul. Ron Paul, a longtime critic of the Fed and author of End the Fed, described interest rate setting by central banks as “price fixing,” equating it to socialist and Marxist economic control. Paul warned that such mechanisms erode personal wealth and undermine economic freedom — a sentiment that aligns closely with Kiyosaki’s long-held concerns. “Fake money lea…

BlackRock’s spot Bitcoin ETF (IBIT) capped off the trading week with another day of inflows, pulling in $356.2 million on May 9. The fund has now extended its inflow streak to 19 consecutive days — its longest run of inflows so far this year. IBIT’s inflow streak has been ongoing since April 14, and has coincided with a volatile Bitcoin (BTC) market, with the asset trading between $83,152 and $103,000 over the period. However, market sentiment has been increasing after the asset reclaimed and held above the $90,000 price on April 23 before reclaiming the $100,000 price on May 8 for the first time since Feb. 1. Bitcoin ETFs ticking along as Bitcoin price spikes Over the past trading week alone, IBIT posted $1.03 billion in inflows, according to Farside data. Prior to the current 19-day stre…

Sovereign Wealth Funds are already gaining exposure to Bitcoin, but significant allocations won’t happen until the United States establishes clearer regulations for the digital assets industry, says SkyBridge founder Anthony Scaramucci. “I think they are buying it, I think they are buying it on the margin,” Scaramucci, former White House director of communications during US President Donald Trump’s first term, said on Anthony Pompliano’s podcast on May 8. Legislation will lead to “large blocks of buying” “I don’t think it is going to be a gigantic groundswell of buying until we greenlight legislation in the United States,” he added. Scaramucci previously said in a February interview with the Financial Times that he expects the US government to propose crypto legislation in November. SWFs a…

Strategy founder Michael Saylor says Bitcoin hasn’t reached $150,000 yet because holders without a long-term outlook have been selling off while a new cohort of investors are beginning to enter the market. “I think we’re going through a rotation right now,” Saylor said on the Coin Stories podcast with Natalie Brunell on May 9. The lack of “10-year investor mindset” led to Bitcoin sell-off Saylor said “lots of non-economically interested parties are rotating out of the asset.” However, at the same time, “a new cohort of investors are entering.” “A lot of Bitcoin, for whatever reason, was left in the hands of the governments and the hands of lawyers, and in the hands of bankruptcy trustees,” he added. Strategy’s Michael Saylor spoke to Natalie Brunell on the Coin Stories podcast. Source: Na…

Key takeaways: ETH price rallied by 22% on May 8, but demand for spot ETH ETFs and derivatives remains muted.  President Trump’s reversal on certain altcoins aligns with ETH’s renewed outlook.  Ether (ETH) posted an impressive 29% gain between May 8 and May 9, likely marking the end of a 10-week bear market that bottomed out at $1,385 on April 9. This sharp move triggered the liquidation of over $400 million in short (sell) ETH futures positions, suggesting that whales and market makers were caught off guard. Despite the surge, traders have maintained a neutral stance in ETH derivatives. Whether this apparent lack of conviction reflects a genuine trend reversal or merely precedes another test of the $2,000 level remains to be seen. Ether 3-month futures annualized premium.

You want to pass variable args to a function, like so: const doSomething = (a: string, b?: string, c?: string): void => {}; However, TS didn't like it... // não bom const args = [['a', 'b', 'c'], ['a', 'b'], ['a']]; args.forEach((arg) => { // A spread argument must either // have a tuple type or be passed // to a rest parameter. ts(2556) vvvvvv doSomething(...arg); }) The problem is that doSomething expects one to three arguments of type string, but arg is typed as string[]. We need to narrow the type down, to match the arguments of doSomething() // bom const properTypedArgs: [a: string, b?: string, c?: string][] = [['a', 'b', 'c'], ['a', 'b'], ['a']]; properTypedArgs.forEach((arg) => { doSomething(...arg); }) This works, but if you don't fancy re-typing the function's argument type defs or don't have it handy, TS utility type got you covered: // ainda melhor const properTypedArgs: Parameters[] = [['a', 'b', 'c'], ['a', 'b'], ['a']]; properTypedArgs.forEach((arg) => { doSomething(...arg); }) That's all!

Hey fellow developer! 👋 Let’s talk about the real journey of building browser extensions: You spend hours crafting the perfect feature, hit "Load Unpacked," and… nothing happens. Or worse—your extension works on your machine but turns into a pumpkin 🎃 on your friend’s browser. Debugging extensions can feel like wrestling gremlins, but don’t panic! I’ve been there (and lived to tell the tale). Let’s break down the most common errors and their fixes so you can get back to shipping magic. 1. “My Extension Doesn’t Load!” (Manifest File Mayhem) The Error: Chrome/Firefox ignores your extension, or you get a cryptic “Invalid manifest” warning.

When working with Kotlin in a cloud environment, especially while integrating AWS S3 and Lambda functions, you may find yourself needing to execute an external JAR file. This often arises, as in your case, when you need to upload data to a third-party vendor. In this article, we will walk through how to call an executable JAR file using Kotlin, including syntax examples and considerations to keep in mind. Understanding How to Execute JAR Files in Kotlin The process of executing a JAR file in Kotlin is not much different from Java, as Kotlin is fully interoperable with Java. You can use the ProcessBuilder class, which allows you to create operating system processes, and invoke JAR files with specific arguments. This capability is particularly useful when you want to run external commands or…  ( 4 min )

Not long ago, artificial intelligence remained hidden behind elite institutions and guarded corporate doors—a secretive world inaccessible to most. Today, these once impervious gates swing wide open, propelled by an unstoppable wave: the power of open-source.

In the past, breakthrough advances took years t…  ( 6 min )

Today's question Create a React application that allows users to create, display and delete blog posts. Solution The first step is to evaluate the boilerplate provided. There are 3 boilerplate files: Home.js import React from "react"; import Input from "./Input"; import PostDisplay from "./PostDisplay"; function Home() { return ( {"Title"} {"Description"} Delete ); } export default PostDisplay; The Home component(file) is provided as the parent component, which manages the state of the application. So, variable states for all blog posts, and a single new blog post will be created. The input component is responsible for creating new blog posts, therefore, the variable states for new blogs will be passed into it after it has been created in the Home component. Then, the PostDisplay component, which handles showing all blog posts, will have the state for all blog posts passed into it.  ( 3 min )

Introduction Are you currently tackling a pathfinding visualizer app using Dart and Flutter? If you're feeling overwhelmed by the programming challenges and specifically by your container colorization logic, you're not alone! In this article, we will go through how to successfully manage color changes for your start and end containers without affecting all elements on the grid. Understanding the Problem In your Flutter application, the objective is to select a 'start' and 'end' container when clicking on the grid, and change their colors accordingly. However, when you try to set the 'start' container color to green, it’s inadvertently updating every container to green, which is not the intended behavior. This issue typically occurs due to how the state and rendering logic is structured in …  ( 4 min )

Wanted to share a very quick on something I learned that was pretty useful to me, so thought it might be useful to others. Here is a scenario that some of you might be familiar with: You have a successful Amazon Q Developer session, and then maybe a few days later, you are trying to recall exactly what you did and how you put your prompts together - what can you do? As it turns out, a recent update to Amazon Q Developer was a big help. In the Amazon Q Developer chat interface, there is a new icon next to the different tabs (its an icon of a click, which when you hover over says "View Chat History") which when you click on this, it will bring back a list of previous chats that have been recorded. What does this mean? In the "~/.aws/amazonq/" directory there is a "history" directory, and looking at it, it contains a number of time/date stamped json files. ├── history │   ├── chat-history-0f97086b54fd7d6128dfd80426dfd63d.json │   ├── chat-history-10d817f64fc99f04badf1568a6c23814.json │   ├── chat-history-deba93a681a17ae26ff2b977acf0ba97.json │   ├── chat-history-fa5091a7425e7938fe770a584b63076e.json │   └── chat-history-no-workspace.json These are what the Amazon Q Developer VSCode plugin now produces as you start using it. That said, because I had deleted my project, and so I was unable to get this from VSCode itself. Aarrgh, I thought to myself. Not to worry though. I still had the files in the history directory. So reviewing these with my favourite json viewer (I knew which file to use, aligning date stamps from these and the code files in my project workspace), allowed me to extract all the history, including prompts and responses. Very handy to know if you want to go back in time. This saved me, so hoping it will help others who are looking to recover what they did.  ( 3 min )

When I started writing code, I thought the goal was perfection. A flawless feature. A zero-bug release. The cleanest, DRYest, most elegant solution to every problem. But if there’s one thing software engineering teaches you—again and again—it’s this: Perfect doesn’t ship. Progress does. Behind every product you love, every app you use daily, and every "it-just-works" moment, there’s a messy history of trade-offs, iterations, rewrites, and late-night breakthroughs. There’s never been a perfect version—only the best version for right now. “If you’re aiming for perfection, you’ll never release,” he says. “But if you aim for learning, you’ll improve with every commit.” That’s the shift that happens when you grow—not just as a coder, but as an engineer. Early Career: Learning the Rules Most engineers begin their journey by learning the rules. Mid-Career: Building Beyond Code As you gain experience, your job evolves. You're not just writing functions—you’re: The Myth of Mastery There’s a moment many engineers hit mid-career: you expect to feel confident, but instead, you feel behind. Late Career: Scaling Impact By the time you’re a senior or staff engineer, the problems you solve are rarely just technical. Letting Go to Grow So what does it really mean to grow as a software engineer? Final Thoughts: We’re All Still Learning No matter where you are in your career—just starting out, mid-level and unsure, or senior and scaling—remember this: You don’t have to be perfect. You just have to keep learning. Great software is built by people who care enough to try, fail, ask, share, and try again. People like Abhishek Desikan, who show that engineering is not just about building products—it’s about building people, teams, and ethical systems that serve others well. “We’re not just writing code,” Desikan reminds us. “We’re writing the story of how people experience technology.” And when we do that with care—even if it’s not perfect—we’re already doing something right.  ( 5 min )

Introduction When developing high-performance applications, managing concurrency efficiently is crucial. In this article, we will address how to ensure that multiple tasks run in parallel on iOS 15 while using Swift's async/await and TaskGroup.

The art of runway walking represents far more than simply moving from point A to point B—it’s a carefully honed skill that conveys brand aesthetic, garment movement, and professional polish. While television and social media often portray modeling as effortless, the reality involves precise technique, body awareness, and adaptability to different show requirements. The walk serves as a model’s primary tool for bringing clothing to life, requiring equal parts discipline and artistry to execute effectively. Proper runway technique begins with posture that appears relaxed yet controlled. The ideal stance starts with shoulders pulled back and down, creating an open chest without appearing stiff. The spine maintains natural alignment from the tailbone through the neck, allowing for fluid moveme…  ( 5 min )

When working with Rust, one of the most significant challenges developers face is understanding how ownership and borrowing interact with threading and memory safety. This article explores a typical pattern when passing pointers to data structures across threads in Rust, particularly in the context of random number generation. We'll analyze a common issue related to use-after-free errors that can arise when implementing parallel processing with threads in Rust, and then provide a clear, step-by-step solution. Understanding the Use-After-Free Issue In your provided code, the primary concern arises from how Rust manages memory and ownership. In Rust, the compiler uses a borrow checker to ensure that references do not outlive the data they point to. When rng is dropped at the end of the main …  ( 5 min )

Ever wondered how Netflix recommends the perfect movie trailer, how security cameras detect unusual activity, or how sports broadcasters create instant highlights? The secret lies in Video AI models. Video AI models enable automated analysis of complex visual data in real-time, enhancing efficiency, accuracy, and decision-making across sports analytics, surveillance, and content creation. With the explosion of video content (~500 hours of video are uploaded to YouTube every minute), video-centric AI applications are more critical than ever. These applications become possible only due to the underlying AI models allowing machines to analyze, interpret, and even predict events from videos. Video AI models enable advanced tasks like object detection, action recognition, and semantic segmenta…  ( 10 min )

The two prevalent cybersecurity threats that internet users face do not appear to be going anywhere soon. If you're an active reader of this series, you already know what they are; malware and phishing. When you think we're going to have a break, you read another news of another discovery, probably where you least expect it. Also, we thought we knew how to detect deepfakes because they could not mimic heartbeats. Now, based on recent research, it turns out that we were wrong.

Hello everyone! Ever wrestled with finding the smallest contiguous subarray within an array that sums up to a given target? It's a classic problem, and today we'll explore two contrasting approaches in JavaScript: the elegant sliding window and the straightforward brute force. Let's dive in! Given an array of positive integers nums and a target integer target, our mission is to find the smallest contiguous subarray whose elements sum up to be greater than or equal to the target. If no such subarray exists, we return 0 (or some other indicator). The most intuitive approach is to consider all possible subarrays. We can achieve this using nested loops: The outer loop iterates through all possible starting indices i from 0 to n-1 (where n is the length of the array). The inner loop iterates …  ( 4 min )

Like a lot of devs, I built a side project that scratched a personal itch: an invoice generator. But instead of going full SaaS startup mode, I treated it as a challenge—build something clean, useful, and fast, with a real login system, server-side PDF generation, and as little overhead as possible. The result is InvoiceDen, a React-based web app hosted on Cloudflare Pages, with backend functionality on an EC2 instance, all for about $8/month. Here’s what I learned architecting it on a shoestring budget — and how you can do something similar without spinning up Kubernetes or draining your wallet. The app is split into a classic frontend + backend setup, but optimized for cost and simplicity. Frontend: React app hosted on Cloudflare Pages Static deploys, global CDN, zero dollars Backend: Sm…  ( 5 min )

It’s a common story: a team launches their application to the cloud, celebrates the deployment and then, weeks later, is shocked by a ballooning cloud bill. What started as a low-cost, high-efficiency architecture suddenly feels bloated and unpredictable. The truth is, most cloud cost spikes don’t come from initial deployments, they come from what happens after. And if you don’t have visibility or automation in place, it’s easy to lose control. Here’s what’s really driving those post-deployment cloud cost spikes and what you can do to stop them with the help of Kuberns. Idle resources that never got turned off After deployment, environments like staging, dev, or feature branches are often left running. Temporary services that were only meant for testing remain active, silently consuming…  ( 4 min )

I recently tried out 5 CMS platforms to use for our blog on sliplane.io and wrote a short section about why I did not like WordPress. Mainly that it’s bloated and plugin-heavy. Some people immediately started firing at me, telling me SEO would be "whack" if I used anything else... as if SEO was a feature toggle in WordPress. But let’s be clear about something: Google doesn’t rank your site based on your CMS! Google doesn’t care if you’re using WordPress, Webflow, Drupal or your content is served from a Google Sheet. Google doesn’t have a CMS bias built in. It doesn’t know how "clean" your CMS feels or cares about how many Yoast plugins you’ve installed. It only sees data. Numbers. Metrics. That's it. Here’s what Google can measure: Page speed – how fast your site loads. Mobile usability …  ( 4 min )

Use case - what it solves So If you're familiar with docker containers so far (if not, read my previous two articles on this), When there's more than 1 container, and they have to interact, there's some things you have to repeat, like: pulling image & creating a container. allocate volumes, pass ENV args, etc to container have all containers running in same network . Now if there's 3,4,5,.. or more, it gets more hectic, see where this is going? Docker compose solves that, by "composing" up your containers config in a file type called "yaml" (its similar to json - a data format, usually for configs). You still have things like Dockerfile and concepts of containers are the same, its just the process that's simpler. A quick example of 3 containers rolling up using docker compose.

If you're learning JavaScript, you've likely come across closures — a concept that's easy to overlook but incredibly powerful. In this post, I'll break down closures using a real-world coding example: computing Fibonacci numbers with memoization. A closure is when a function remembers the variables from its lexical scope, even after the outer function has finished executing. In other words, inner functions can "close over" variables defined in an outer function — keeping them alive between calls. Let’s start with a simple (but inefficient) recursive Fibonacci implementation: function fib(n) { if (n <= 1) return n; return fib(n - 1) + fib(n - 2); } console.log(fib(10)); // 55 This works, but it's horribly inefficient for large n due to repeated calculations. Let’s use a closure to store previously computed Fibonacci numbers (aka memoization) and avoid redundant work. function createFibonacci() { const memo = {}; function fib(n) { if (n in memo) { return memo[n]; // Return cached result } if (n <= 1) { memo[n] = n; } else { memo[n] = fib(n - 1) + fib(n - 2); } return memo[n]; } return fib; } const fibonacci = createFibonacci(); console.log(fibonacci(10)); // 55 console.log(fibonacci(50)); // 12586269025 — much faster due to caching! memo is defined once inside createFibonacci() and persists across calls to fib() because of closure. Even after createFibonacci() has returned, the fib() function still remembers the memo object. This is the closure in action: the inner function keeps access to its outer scope. Closures allow us to: Preserve state across function calls without polluting the global scope. Create factory functions like createFibonacci() that generate self-contained logic. Enable powerful patterns like memoization, function factories, and data encapsulation. Closures aren't just theoretical — they’re a practical tool for writing clean, efficient JavaScript. Have any cool uses of closures? Drop them in the comments!  ( 3 min )

In Go version 1.24, the encoding/json package introduced the omitzero tag, making the behavior of ignoring zero-value fields more explicit and customizable. This article provides a detailed explanation of how to use the omitzero tag. omitzero Tag The omitzero tag is used to control which zero-value fields should be omitted when serializing Go objects into JSON. Unlike the omitempty tag, which omits empty-value fields, zero values and empty values, while similar, are not equivalent in Go. For example: For the time.Time type, the zero value is "0001-01-01T00:00:00Z", which is not considered an empty value. For a slice field like IntSlice []int, both [] and nil are considered empty values. omitzero Precise control: Explicitly omits zero-value fields, rather than empty-value fields. Cust…  ( 4 min )

Web Cache Deception is a vulnerability first described in 2017. It occurs when a caching system — such as a reverse proxy or CDN — can be tricked into caching sensitive, dynamic content that should only be delivered to authenticated users but ends up being publicly available. This is usually due to poorly thought-out or inconsistent configurations in how the cache interprets and stores different types of requests. Many caching systems have simple rules for deciding what can and cannot be cached. A common pattern is to only cache "static" files — such as those ending in .js, .css, .png, .ico, etc. The problem arises when the cache relies solely on the structure of the URL path to make this decision, ignoring the actual behavior of the server behind it. Imagine this: the caching system is in…  ( 4 min )

Modern web apps often include dynamic elements like modals, tooltips, dropdowns, and popovers. These UI components need to float above everything else, but positioning them correctly can get tricky, especially when they're deeply nested in the DOM. That’s where React Portals come in. React Portals let you render components outside the normal DOM hierarchy, making it easier to handle z-index, positioning, and layering—without complicating your component logic. In this guide, you’ll learn what React Portals are, why they matter, and how to use them to build cleaner, more flexible UIs. React Portals let you render a component outside its parent DOM node—perfect for things like modals or tooltips that need to break out of the usual layout, while still staying in the same React tree.

Introduction In C#, anonymous types are useful for encapsulating a set of read-only properties into a single object without explicitly defining a class. However, developers often seek better ways to declare these types without relying on creating instances, which can lead to less readable and maintainable code. This article explores various methods and optimizes the solution for anonymous types in C# while avoiding hacky implementations. Understanding Anonymous Types in C# Anonymous types in C# allow you to create simple objects without creating a separate class definition. However, creating instances as seen in your initial example can appear convoluted and detracts from clarity and maintainability. The issue arises when developers need a type to be used across different scopes without re…  ( 4 min )

If you're building anything beyond a toy application, you will hit scaling bottlenecks. When your database starts groaning under load, two architectural strategies emerge as lifelines: partitioning and sharding. But they're not interchangeable—misusing them can make your scaling problems worse. Let's break them down technically. Partitioning: Splitting Data Within a Single Database What it is: Partitioning (often called horizontal partitioning) divides a table into smaller segments within the same database instance, based on a partition key (e.g., user_id, date). How it works: Range Partitioning: Data split by value ranges (date = '2023-01-01'). List Partitioning: Explicit mappings (region IN ('east', 'west')).

I have a bit of an obsession with finding the fastest way to launch apps. My goal is to be able to create fully functional MVP's and proofs of concept in less than a day. That means being able to spin up a backend and then implement a frontend as efficiently as possible. For the backend, PocketBase has been my favorite lately. On the frontend I am still trying to find a winner. I like Quasar (VueJS + Capacitor) which is fantastic for web apps, but falls a bit short for mobile apps. I've been eyeing React Native lately especially since Expo offers a ton of great plugins like Location and also supports remote updates. Unfortunately I fell well short of being able to create a basic app in less than a day with these two. After clearing a few roadblocks, however, I think you'll be able to move …  ( 5 min )

When I have the freedom to choose, and it fits the project, I often reach for Kotlin. It makes applying core principles straightforward in most cases. // Single Responsibility Principle class ReportGenerator { fun generate() { /* ... */ } } class ReportPrinter { fun print(report: ReportGenerator) { /* ... */ } } // Open/Closed Principle open class Shape { open fun area(): Double = 0.0 } class Circle(val radius: Double) : Shape() { override fun area() = Math.PI * r…  ( 5 min )

Albert Einstein once said, “I have no special talents. I am only passionately curious.” I’ve worked with a lot of engineers over the years. From juniors trying to get their first PR merged to seniors who basically run the entire company. And the best ones, the ones who constantly level up, spot bugs before they happen, and seem to "just get it," aren’t always the smartest in the room. But they all have one thing in common. They are endlessly curious. They go down rabbit holes nobody asked them to go down. They read the source code. They poke at edge cases. They don’t stop at “it works.” They ask, “why and how does it work?” Raw knowledge is easy to come by now. If you want to learn Kubernetes, there’s a 12-hour crash course.

I was exploring the MDN docs and stumbled onto the newer CompressionStream API which enables a couple encodings to compress data streams; namely the popular classic GZIP, and a basic Deflate. This is a neat first step for the client, but better newer compression encodings exist; these may be forth-coming to the native api one day; Brotli and ZSTD come to mind as the top current ones. I wanted to test out all the available options I could find to see for myself. So first I searched and was able to find these libs: zstd-wasm zstd-js lz-string brotlijs High level I reckon ZSTDjs, ZSTDwasm, and then Brotli are top performers... here a screenshot of my findings and the repo: https://github.com/jswhisperer/compression-compare  ( 3 min )

If you're new to clang-format and are looking for the best way to maintain your code's structure, you've come to the right place. Clang-format is a popular tool used for formatting C and C++ code, and adjusting its behavior can sometimes be tricky. Understanding Clang-Format Behavior Clang-format is designed to enforce consistency in code style, which often leads to unexpected formatting changes. The situation you described, where struct definitions are condensed into single lines when they could be multi-line, is a common frustration among developers. When you have a structure defined as: typedef struct { a, b, c } my_struct_t; Clang-format may alter it to: typedef struct { a, b, c } my_struct_t; This happens even when your configuration sets a ColumnLimit of 100.

egretting Some Tool Choices At one point, I became so frustrated that I took a step back and created a rather lengthy markdown file to document my expected behaviors of the page, and asked Cursor to start over based on these new requirements. I had hoped the more thorough context would result in a better initial implementation, but to be honest, it was little better than what I had before. In the end, it was just continuous iteration that finally got me to something approaching usable. Or was it? Before I started this project, I asked LLMs for feedback on suggested frameworks. Based on various responses, I ultimately went with React because I thought that might directly translate into something I could use in future professional endeavors.

In the world of web development, HTTP status codes are the backbone of communication between clients (like browsers or mobile apps) and servers. These codes provide vital clues about the success or failure of HTTP requests—whether it's loading a page, sending data, or interacting with an API. Understanding these codes not only improves debugging but also enhances user experience and application stability. Here’s a practical guide to the most common HTTP status codes and how they are used in programming and real-world deployment: This is the most common and desirable response. It means the request was successful and the server returned the expected data. Use Case in JavaScript (Fetch API): fetch('https://api.example.com/user/123') .then(response => { if (response.status === 200) { …  ( 5 min )

As artificial intelligence continues to reshape the software development landscape, tools like Model Context Protocol (MCP) and Codium AI (now Qodo) are carving out unique roles. While both are engineered to boost productivity and intelligence in development workflows, they function in fundamentally different ways and serve distinct purposes. Created by Anthropic, MCP is an open-source protocol designed to help AI agents communicate, share knowledge, and interact with external systems. Rather than focusing on code generation, MCP serves as a coordination layer that facilitates secure and intelligent collaboration between AI agents and the external world—such as tools, APIs, or cloud platforms. Key Features: Built on JSON-RPC 2.0 for standardized communication Enables multi-agent interactio…  ( 4 min )

As AI technologies continue to evolve, developers are constantly seeking ways to enhance and streamline interactions with large language models (LLMs). One significant advancement in this space is the Model Context Protocol (MCP), recently introduced by Anthropic, and its implementation through MCP servers. In this article, I'll share my findings and experiences with MCP servers, exploring what they are, why they matter, and how you can get started with them. The Model Context Protocol (MCP) is a standardized communication protocol that defines how applications interact with language models while efficiently managing context. It was designed to address the limitations of traditional API interactions with LLMs, particularly around context management. The protocol enables developers to creat…  ( 6 min )

This post is also available in Portuguese: Read in Portuguese Hello! I'm Gustavo — a back-end software developer with a passion for Java, Python, automation, software design, and more recently, using AI for practical application. I'm beginning my technical writing here, sharing some of the knowledge and experience derived from projects that I've been developing myself. I've also always been a learn-by-doing kind of person — break things, repair them, and work with actual issues. So in addition to picking up new tools, I thought I'd blog the experience along the way — perhaps it's helpful to someone out there, or at least provokes some interesting discussions in here. Ever feel lost in oceans of technical documentation, or spend too much time wondering how a codebase really works? That's wh…  ( 5 min )

“I'm sick of babysitting ec2.” Security patches, instance health checks, autoscaling headaches — when did server management become your main job? You got into this to build apps, not to stay up at night restarting failed instances. That’s exactly how I felt. Burned out from constantly tending to EC2, I eventually discovered Fargate — and it was a game-changer. At one point, I was stuck in the same loop: wrestling with complex scaling rules, dealing with unexpected traffic spikes, and getting midnight alerts about instance failures. Then I found ECS + Fargate. “Wait a minute… I don’t need to manage servers anymore?” That realization was like a weight lifting off my shoulders. In this article, I’ll walk you through what ECS, Fargate, and ECR are — and more importantly, why they matter. Wheth…  ( 4 min )

Introduction Handling form validations effectively is a common requirement in Angular applications, especially when using Material Design components like . When a user encounters multiple validation errors on a form input, it can sometimes lead to a chaotic user experience, particularly when the error messages overflow and overlap other UI elements. This article explores how to manage excessive validator messages gracefully and cleanly, giving user-friendly feedback without cluttering the interface. Understanding the Problem When displaying validator errors, the typical approach involves listing all the error messages directly below the input field. In scenarios with multiple errors, this can lead to overflowing content that disrupts the layout and makes it difficult for us…  ( 4 min )
